Romanovski polynomials are a class of orthogonal polynomials that generalize classical orthogonal polynomials such as Hermite, Laguerre, and Legendre polynomials. They are named after the Russian mathematician A. V. Romanovski, who studied these polynomials in the context of certain orthogonal polynomial systems. These polynomials can be characterized by their orthogonality properties with respect to specific weight functions on defined intervals, and they satisfy certain recurrence relations.
The Rook polynomial is a combinatorial polynomial used in the study of permutations and combinatorial objects on a chessboard-like grid, specifically related to the placement of rooks on a chessboard. The Rook polynomial encodes information about the number of ways to place a certain number of non-attacking rooks on a chessboard of specified dimensions.
In mathematics, particularly in complex analysis and algebra, a root of unity is a complex number that, when raised to a certain positive integer power \( n \), equals 1.
The Rosenbrock function, often referred to as the Rosenbrock's valley or Rosenbrock's banana function, is a non-convex function used as a performance test problem for optimization algorithms. It is defined in two dimensions as: \[ f(x, y) = (a - x)^2 + b(y - x^2)^2 \] where \(a\) and \(b\) are constants.
The Sister Beiter conjecture is a conjecture in the field of number theory, specifically relating to the distribution of prime numbers. It was proposed by the mathematician Sister Mary Beiter, who is known for her work in this area. The conjecture suggests that there is a certain predictable pattern or behavior in the distribution of prime numbers, particularly regarding their spacing and density within the set of natural numbers.
The Theory of Equations is a branch of mathematics that deals with the study of equations and their properties, solutions, and relationships. It primarily focuses on polynomial equations, which are equations in which the unknown variable is raised to a power and combined with constants. Here are some key concepts within the Theory of Equations: 1. **Polynomial Equations**: These are equations of the form \( P(x) = 0 \), where \( P(x) \) is a polynomial.
The Tutte polynomial is a two-variable polynomial associated with a graph, which encodes various combinatorial properties of the graph. It is named after the mathematician W. T. Tutte, who introduced it in the 1950s.
The Laguerre–Forsyth invariant is a concept in the field of differential geometry and the theory of differential equations. It arises in the context of studying the properties of certain mathematical objects under transformations, particularly in the context of higher-order differential equations. The Laguerre–Forsyth invariant specifically relates to the form of a class of differential equations known as ordinary differential equations (ODEs), particularly those of the type that can be transformed into a canonical form by appropriate changes of variables.
José Mendes is an accomplished physicist known for his work in statistical physics, complex systems, and networks. He has made significant contributions to understanding phenomena such as phase transitions, dynamics on complex networks, and the interplay between individual behavior and collective dynamics in systems. Mendes has published numerous papers in prominent scientific journals and has collaborated with various researchers in the field.
An atomic sentence, also known as an atomic proposition or atomic statement, is a basic declarative sentence in formal logic that does not contain any logical connectives or operators (such as "and," "or," "not," "if...then," etc.). Instead, it expresses a single, indivisible statement that is either true or false. For example, the following are atomic sentences: - "The sky is blue." - "2 + 2 = 4.
In mathematical logic, "judgment" can refer to the process of forming a conclusion based on the evaluation of certain premises or propositions. It's a way to express truth values or the correctness of statements within a logical system. While the term “judgment” can have various meanings depending on the context, it often appears in discussions of type theory and proof systems, such as in the work of logicians and computer scientists studying formalized languages and systems of logic.
"Labour of Love II" is the title of a series of artworks by British artist and social activist, Sir Anthony Caro. His work often revolves around themes of labor and love, exploring the relationship between the two concepts. However, to provide the most relevant answer, it is important to note that the terms "Labour of Love II" can refer to different contexts, including art, literature, or even music.
The Drinker Paradox is a concept in probability theory and combinatorial geometry that concerns the intersection of random sets in a geometric context. Specifically, it illustrates an interesting property of certain geometric objects and the probabilities associated with their intersections. The paradox can be described as follows: Imagine a circle (often referred to as a "drinker") and consider a number of points (often represented as "drunkards") that are uniformly and randomly distributed on the circumference of this circle.
In the context of formal logic, mathematics, and computer science, the concepts of **free variables** and **bound variables** are important in understanding the structure of expressions, particularly in terms of quantification and function definitions. ### Free Variables A **free variable** is a variable that is not bound by a quantifier or by the scope of a function. In simpler terms, free variables are those that are not limited to a specific context or definition, meaning they can represent any value.
Intensional logic is a type of logic that focuses on the meaning and intention behind statements, as opposed to just their truth values or reference. Unlike extensional logic, which primarily deals with truth conditions and the relationships between objects and their properties, intensional logic takes into account the context, use, and meaning of the terms involved. Key features of intensional logic include: 1. **Intensions vs.
Monadic predicate calculus is a type of logical system that focuses on predicates involving only one variable (hence "monadic"). In mathematical logic, predicate calculus (or predicate logic) is an extension of propositional logic that allows for the use of quantifiers and predicates. In monadic predicate calculus, predicates are unary, meaning they take a single argument. For example, if \( P(x) \) is a predicate, it can express properties of individual elements in a domain.
In logic and programming, "scope" refers to the region or context within which a particular variable, function, or symbol is accessible and can be referenced. It determines the visibility and lifetime of variables and functions in a given program or logical expression. ### Types of Scope 1. **Lexical Scope**: Also known as static scope, this is determined by the physical structure of the code. In languages with lexical scoping, a function's scope is determined by its location within the source code.
In logic, a second-order predicate is an extension of first-order logic that allows quantification not only over individual variables but also over predicates or sets of individuals. In first-order logic, you can have statements that quantify over objects in a domain (like "for every \(x\), \(P(x)\)").
Janet Brown Guernsey is an American artist known for her work as a painter, printmaker, and sculptor. Her art often combines various influences and mediums, exploring themes such as nature, identity, and the human experience. Specifically, she has gained recognition for her layered techniques and vibrant color palettes, which can be seen in her paintings and printmaking projects.
Bennett's inequality is a result in probability theory that provides a bound on the tail probabilities of sums of independent random variables, particularly in the context of bounded random variables. Specifically, Bennett's inequality is useful for establishing concentration results for random variables that are bounded and centered around their expected value.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
