Dominique Foata is a French mathematician known for his contributions to combinatorial mathematics and particularly to the field of combinatorial theory and enumeration. He has worked on various topics, including generating functions, combinatorial identities, and applications of combinatorics in other areas of mathematics. Foata is also recognized for his work on permutations and their properties.
Hugo Hadwiger was a notable Swiss mathematician known for his contributions to several areas of mathematics, particularly in the fields of topology, geometry, and graph theory. He is perhaps best known for Hadwiger's theorem and Hadwiger's conjecture, which relate to the properties of graph colorings and the connections between different types of geometric figures. His work has had a lasting impact on mathematical research and theory.
The Australasian Journal of Combinatorics is a peer-reviewed academic journal that focuses on research in combinatorics, which is a branch of mathematics dealing with the counting, arrangement, and combination of objects. Established in 1990, the journal publishes original research papers, survey articles, and other contributions related to various aspects of combinatorial theory and applications.
A "partial word" generally refers to a segment or piece of a word that is not complete. It can involve a few letters of a word that may not fully convey its meaning or pronunciation. Partial words are often used in contexts such as: 1. **Word Formation**: When creating new words or forms, prefixes or suffixes might be considered partial words.
The \( Q \)-theta function is a special function that is a generalization of the classical theta functions and appears in various areas of mathematics, particularly in number theory, combinatorics, and the theory of partitions.
The Monomial Conjecture, proposed by mathematician G. G. Szegő in 1939 and later expanded upon, concerns the topology and combinatorial mathematics of polytopes and their connection to the algebraic properties of certain spaces. It posits that certain types of generating functions, particularly those related to monomials in polynomial rings, can be understood through the topology of specific polytopes.
An "acceptable ring" is not a standard term in mathematics, but it could refer to a certain type of algebraic structure known as a "ring" in abstract algebra. In general, a ring is a set equipped with two binary operations that satisfies specific properties.
The Auslander–Buchsbaum formula is a significant result in commutative algebra and homological algebra that relates the projective dimension of a module to its depth and the dimension of the ring over which the module is defined. Specifically, it provides a way to compute the projective dimension of a finitely generated module over a Noetherian ring.
A **Buchsbaum ring** is a type of commutative ring that has certain desirable properties, particularly in the context of algebraic geometry and commutative algebra. It is named after the mathematician David Buchsbaum.
Cluster algebras are a class of commutative algebras that were introduced by mathematician Laurent F. Robbin in 2001. They have a rich structure and have connections to various areas of mathematics, including combinatorics, representation theory, and algebraic geometry. ### Key Features of Cluster Algebras 1. **Clusters and Variables**: A cluster algebra is constructed using sets of variables called "clusters." Each cluster consists of a finite number of variables.
A complete intersection is a concept from algebraic geometry that refers to a type of geometric object defined by the intersection of multiple subvarieties in a projective or affine space. Specifically, a variety \( X \) is called a complete intersection if it can be defined as the common zero set of a certain number of homogeneous or non-homogeneous polynomial equations, and if the number of equations is equal to the codimension of the variety.
The term "ideal norm" can have different meanings depending on the context. Here are a couple of interpretations based on various fields: 1. **Mathematics/Statistics**: In the context of mathematics, particularly in functional analysis and linear algebra, an "ideal norm" could refer to the notion of a norm that satisfies certain properties or conditions ideal for a given space.
In the context of ring theory, an irreducible ring is typically referred to as a ring that cannot be factored into "simpler" rings in a specific way.
"Jinkōki" (人工木) translates to "artificial wood" in Japanese and refers to materials that simulate the properties and appearance of natural wood. It is often used in construction and furniture manufacturing to create durable, aesthetically pleasing products while minimizing the dependency on natural wood resources. The term could also refer to composite materials made from wood fibers and synthetic resins.
In commutative algebra, a **local ring** is a ring that has a unique maximal ideal. A **unibranch local ring** is a specific type of local ring characterized by the properties of its completion and its ramification properties. More formally, a local ring \( (R, \mathfrak{m}) \) is called a **unibranch local ring** if its closure in its completion is a domain that is unibranch.
The Stone–Čech compactification is a mathematical concept in topology that extends a topological space to a compact space in a way that retains certain properties of the original space. It is named after mathematicians Marshall Stone and Eduard Čech. ### Definition Let \( X \) be a completely regular topological space.
"AI-complete" is a term used in the field of artificial intelligence to describe problems that are as hard as the general problem of artificial intelligence itself. Essentially, a problem is considered AI-complete if solving it would require the full capabilities of artificial intelligence, including aspects like perception, reasoning, learning, and possibly even consciousness. The idea is that if one could solve an AI-complete problem, they would likely also have created a system that possesses general intelligence, akin to human cognitive abilities.
The Pinkerton Lecture is an academic event that typically features a distinguished speaker who addresses topics related to civil liberties, constitutional law, or similar areas of interest. The lecture is often part of a series established to honor significant contributions to public discourse and scholarship in these fields. Various institutions, such as universities or law schools, may host the Pinkerton Lecture, and it could focus on contemporary issues, historical perspectives, or theoretical discussions relevant to civil rights and liberties.
Poplog is an integrated development environment (IDE) and a programming environment primarily aimed at artificial intelligence (AI) research and development. It was developed in the 1980s at the University of Sussex in the UK and supports multiple programming languages, including: 1. **Pop11**: A programming language similar to Lisp and used extensively in AI. It offers features for symbolic computation and list processing. 2. **Prolog**: A logic programming language commonly associated with AI.
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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
