The **clique-sum** is a graph operation used primarily in graph theory, particularly in the study of graph properties and constructions. This operation allows you to combine two graphs in a way that preserves some of their characteristics while introducing new structure. Here’s how the clique-sum operates: 1. **Graphs Involved**: You start with two graphs, say \(G_1\) and \(G_2\).
A medial graph is a concept used in the field of computational geometry, particularly in the areas of shape analysis and mesh processing. It represents the intrinsic structure of a geometric shape or surface. In essence, the medial graph captures the topological and geometrical characteristics of the shape's skeleton or centerlines. It is achieved through various methods, which typically involve identifying points that are equidistant from the boundary of the shape.
Graceful labeling is a concept in graph theory related to labeling the vertices of a graph in a specific way that satisfies certain criteria. A graph is said to be gracefully labeled if it can be assigned labels (usually integers) to its vertices such that the following conditions are met: 1. The labels assigned to the vertices are distinct integers, typically taken from the set {0, 1, 2, ...
The term "induced path" typically arises in various contexts, such as in mathematics, particularly in graph theory. In graph theory, an **induced path** refers to a specific kind of subgraph of a graph.
In the context of graph theory, a **minimum cut** refers to a specific type of partitioning of a graph that separates the vertices into two distinct subsets while minimizing the total weight of the edges that cross between these two subsets. ### Key Concepts: - **Graph**: A collection of vertices (nodes) connected by edges (links). - **Cut**: A cut in a graph is a way of dividing the graph's vertices into two disjoint subsets.
A configuration graph is a type of graph used to represent the states and transitions of a system, particularly in the context of distributed systems, robotics, or combinatorial problems. In general, configuration graphs help visualize how different configurations (or states) of a system can transition from one to another based on certain rules or actions.
A disjunctive graph is a concept often encountered in the fields of graph theory and computer science, particularly in relation to representation and analysis of logical expressions, automata, and certain types of optimization problems. However, the term "disjunctive graph" is not universally defined, and its meaning can vary based on the context.
The Ingredient-Flavor Network is a concept that explores the relationships between various food ingredients and their associated flavors. It is often represented as a network where ingredients serve as nodes and their flavor characteristics or pairings are represented as edges connecting these nodes. This network can help chefs, food scientists, and food enthusiasts to understand which ingredients complement each other based on shared flavor compounds or culinary traditions.
A Smith graph is a specific type of graph in graph theory. It is a 5-regular graph on 14 vertices, meaning that each vertex has exactly 5 edges connecting it to other vertices. The Smith graph has a unique property: it is both vertex-transitive and edge-transitive, which means that the structure looks the same from any vertex and from any edge. Certain characteristics of the Smith graph include: - It has 14 vertices and 35 edges.
Blockmodeling is a methodological approach used in social network analysis to simplify and analyze complex social networks by grouping nodes (typically individuals or organizations) into blocks based on their structural characteristics and relationships. The primary goal of blockmodeling is to reveal patterns and underlying structures within a network, making it easier to understand the relationships among actors.
The Glivenko–Cantelli theorem is a fundamental result in probability theory and statistics that deals with the convergence of empirical distribution functions to the true distribution function of a random variable.
The Law of the Iterated Logarithm (LIL) is a result in probability theory that describes the asymptotic behavior of sums of independent and identically distributed (i.i.d.) random variables. It provides a precise way to understand the fluctuations of a normalized random walk. To put it more formally, consider a sequence of i.i.d.
A mathematical series is the sum of the terms of a sequence of numbers. It represents the process of adding individual terms together to obtain a total. Series are often denoted using summation notation with the sigma symbol (Σ). ### Key Concepts: 1. **Sequence**: A sequence is an ordered list of numbers. For example, the sequence of natural numbers can be written as \(1, 2, 3, 4, \ldots\).
A hyperinteger is a term that can refer to a variety of concepts depending on the context, but it is not widely recognized in standard mathematical terminology. It is sometimes used in theoretical or abstract mathematical discussions, particularly in the realm of advanced number theory or hyperoperations, where it might denote an extension or generalization of integers. In some contexts, "hyperinteger" is used to describe a hypothetical new type of integer that exceeds traditional integer definitions, possibly involving concepts from set theory or computer science.
Formal distribution typically refers to a distribution that is mathematically defined and adheres to specific statistical properties. In the context of probability and statistics, it can relate to several concepts: 1. **Probability Distribution**: A formal probability distribution describes how probabilities are allocated over the possible values of a random variable. Common examples include: - **Normal Distribution**: Characterized by its bell-shaped curve, defined by its mean and standard deviation.
A line integral is a type of integral that calculates the integral of a function along a curve or path in space. It is particularly useful in physics and engineering, where one often needs to evaluate integrals along a path defined in two or three dimensions.
The Szegő kernel, denoted often as \( S(z, w) \), is a special kernel function that arises in the context of complex analysis, particularly in relation to the theory of reproducing kernel Hilbert spaces (RKHS) and the study of functions on the unit disk.
Zeros and poles are fundamental concepts in the field of complex analysis, particularly in control theory and signal processing, where they are used to analyze and design linear systems. ### Zeros: - **Definition**: Zeros are the values of the input variable (often \( s \) in the Laplace domain) that make the transfer function of a system equal to zero.
The term "effective domain" can have different meanings depending on the context in which it is used. Here are a couple of interpretations: 1. **Mathematics and Computing**: In mathematics, particularly in the context of functions or algorithms, the "effective domain" refers to the set of inputs for which a function is defined and produces meaningful outputs. This can differ from the theoretical domain, which might include inputs that lead to undefined or nonsensical results.

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.
