The Leibniz operator is a differential operator used in the context of calculus, particularly in the formulation of differentiating products of functions. It is named after the mathematician Gottfried Wilhelm Leibniz, who made significant contributions to the development of calculus.
In topology, the symmetric product of a topological space \( X \), denoted as \( S^n(X) \), is a way to construct a new space from \( X \) that encodes information about \( n \)-tuples of points in \( X \) while factoring in the notion of indistinguishability of points.
The degree of an algebraic variety is a fundamental concept in algebraic geometry that provides a measure of its complexity and size. Specifically, it reflects how intersections with linear subspaces behave in relation to the variety.
As of my last knowledge update in October 2021, Anna Romanowska could refer to a specific individual or figure in various contexts, but there is not a widely recognized or notable person by that name in public records or popular culture. It is possible that Anna Romanowska could be a private individual, a professional in a certain field, or a fictional character.
Efim Zelmanov is a prominent mathematician known for his contributions to the field of algebra, particularly in the area of group theory. Born on November 16, 1941, in Tashkent, Uzbekistan, he is best known for his work on the structure of groups and for proving the restricted Burnside problem in the 1990s, which garnered significant attention in the mathematical community.
Gauss's Pythagorean right triangle proposal refers to a problem in number theory that connects to Pythagorean triples—that is, sets of three positive integers \( (a, b, c) \) that satisfy the equation \( a^2 + b^2 = c^2 \).
A **power automorphism** is a concept from the field of group theory, a branch of mathematics. To understand it, we first need to define a few key terms: - **Automorphism**: An automorphism is a function from a mathematical structure to itself that preserves the structure's operations.
A hydrodynamic seal is a type of sealing mechanism used in various applications to prevent fluid leakage between rotating or moving components while allowing relative motion. This type of seal relies on fluid dynamics—specifically, the hydrodynamic pressure generated by the fluid to create an effective sealing force.
Sorin Popa can refer to different individuals or contexts, as the name may belong to various people. Without specific context, it's difficult to determine which Sorin Popa you are referring to. There may be noted individuals in fields such as sports, academia, or business with that name.
Fair division protocols are mathematical and algorithmic methods used to allocate resources among multiple parties in a way that is considered fair and equitable. These protocols are often applied in various contexts, such as dividing goods, resources, or even tasks among individuals, families, or groups. The objective is to ensure that each participant feels that they have received a fair share based on agreed-upon criteria.
Digit-by-digit algorithms are computational methods used primarily to perform arithmetic operations such as addition, subtraction, multiplication, and division on numbers, particularly large numbers, by processing one digit at a time. These algorithms can be especially useful in contexts where numbers cannot be easily handled by conventional data types due to their size, such as in cryptography or arbitrary-precision arithmetic. ### Key Characteristics 1.
Distributed tree search refers to a computational method used to solve problems that can be represented as trees, leveraging a distributed system to improve efficiency and scalability. It is commonly employed in fields like artificial intelligence, operations research, and optimization problems, particularly in contexts where the search space is large. In a typical tree search, nodes represent states or decisions, and branches represent the possible actions or transitions between these states.
Kinodynamic planning is a concept in robotics and motion planning that involves considering both the kinematics (the geometric aspects of motion) and the dynamics (the forces and torques that enable motion) of a robot or a moving object. The goal of kinodynamic planning is to find a feasible trajectory for a robot that satisfies both its physical constraints and the environment's constraints.
Otto E. Neugebauer (1899–1990) was a prominent Austrian-American mathematician and historian of mathematics, best known for his work in the fields of ancient and medieval astronomy and mathematics. His research focused particularly on the mathematical practices and astronomical models of ancient cultures, including those in Babylon, Egypt, and Greece. Neugebauer's contributions include the study of cuneiform texts and the mathematical ideas embedded in them, along with the development of concepts in ancient science.
The Shapiro-Senapathy algorithm is a method used in the field of data classification and clustering, particularly for analyzing and processing time series data. It is named after its creators, Dr. Walter Shapiro and Dr. P. R. Senapathy. The algorithm is designed to identify patterns and trends within data, making it useful for various applications, including financial analysis, signal processing, and any context where temporal data is examined.
Pointer jumping is a technique used in computer programming, particularly in the context of data structures and algorithms, to efficiently navigate or manipulate linked structures such as linked lists, trees, or graphs. While the term is not universally defined, it generally refers to two main concepts: 1. **Efficient Navigation**: Pointer jumping can refer to the method of using pointers to quickly skip over certain nodes or elements in a data structure.
Atmospheric Pressure Photoionization (APPI) is an ionization technique commonly used in mass spectrometry. It is particularly useful for the analysis of a wide range of compounds, including those that are non-polar or semi-polar, which often do not ionize well using traditional techniques like electrospray ionization (ESI) or matrix-assisted laser desorption/ionization (MALDI).

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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
