Algebraic structures are fundamental concepts in abstract algebra, a branch of mathematics that studies algebraic systems in a broad manner. Here’s an outline of key algebraic structures: ### 1. **Introduction to Algebraic Structures** - Definition and significance of algebraic structures in mathematics. - Examples of basic algebraic systems. ### 2. **Groups** - Definition of a group: A set equipped with a binary operation satisfying closure, associativity, identity, and invertibility.
The Grothendieck group is an important concept in abstract algebra, particularly in the areas of algebraic topology, algebraic geometry, and category theory. It is used to construct a group from a given commutative monoid, allowing the extension of operations and structures in a way that respects the original monoid's properties.
A double groupoid is a mathematical structure that generalizes the concept of a groupoid. To understand what a double groupoid is, it helps to first clarify what a groupoid is. ### Groupoid A **groupoid** consists of a set of objects and a set of morphisms (arrows) between these objects satisfying certain axioms. Specifically: - Each morphism has a source and target object.
In mathematics, the concept of **essential dimension** is a notion in algebraic geometry and representation theory, primarily related to the study of algebraic structures and their invariant properties under field extensions. It provides a way to quantify the "complexity" of objects, such as algebraic varieties or algebraic groups, in terms of the dimensions of the fields needed to define them.
A finitely generated abelian group is a specific type of group in abstract algebra that has some important properties. 1. **Group**: An abelian group is a set equipped with an operation (often called addition) that satisfies four properties: closure, associativity, identity, and inverses. Additionally, an abelian group is commutative, meaning that the order in which you combine elements does not matter (i.e.
In abstract algebra, a **semigroup** is a fundamental algebraic structure consisting of a set equipped with an associative binary operation. Formally, a semigroup is defined as follows: 1. **Set**: Let \( S \) be a non-empty set.
The term "Right Group" can refer to different organizations or movements depending on the context, such as political or ideological groups that advocate for conservative or right-leaning policies. However, it is not a widely recognized or specific organization without additional context. If you're referring to a particular group, organization, or movement (e.g.
Baddari Kamel is a traditional dish from the Middle East, particularly associated with Palestinian cuisine. It consists of lamb (or sometimes other meats) that is slow-cooked with vegetables and spices, typically served over rice. The dish is known for its rich flavors and fragrant spices, which can include ingredients like cumin, coriander, and cinnamon.
Pidgin code generally refers to a type of programming language that is designed to be simple, often using a limited set of vocabulary or commands to allow for easy communication between developers or with systems. However, the term “Pidgin” can also refer to a broader context, such as: 1. **Pidgin Languages**: In linguistics, a pidgin is a simplified language that develops as a means of communication between speakers of different native languages.
"Iota" and "Jot" are terms often used in different contexts, and their meanings can vary based on the subject matter. 1. **Iota**: - **Greek Alphabet**: In the Greek alphabet, Iota (Ι, ι) is the ninth letter. In the system of Greek numerals, it has a value of 10.
Structured English is a method of representing algorithms and processes in a clear and understandable way using a combination of plain English and specific syntactic constructs. It is often used in the fields of business analysis, systems design, and programming to communicate complex ideas in a simplified, readable format. The key objective of Structured English is to ensure that the logic and steps of a process are easily understood by people, including those who may not have a technical background.
The Kolmogorov structure function is a mathematical concept used in turbulence theory, particularly within the framework of Kolmogorov's theory of similarity in turbulence. It provides a way to describe the statistical properties of turbulent flows by relating the differences in velocity between two points in the fluid.
"Works" in the context of algorithmic trading typically refers to how algorithmic trading systems are designed to operate, function, and deliver results in financial markets. Algorithmic trading involves the use of computer algorithms to automate trading strategies and execute trades at speeds and frequencies that are impossible for human traders.
Sequence alignment algorithms are computational methods used to identify and align the similarities and differences between biological sequences, typically DNA, RNA, or protein sequences. The primary goal of these algorithms is to find the best possible arrangement of these sequences to determine regions of similarity that may indicate functional, structural, or evolutionary relationships. There are two main types of sequence alignment: 1. **Global Alignment**: This approach aligns the entire length of two sequences.
High-frequency trading (HFT) is a form of algorithmic trading characterized by the use of advanced technological tools and strategies to execute trades at extremely high speeds and high volumes. HFT firms use powerful computers and complex algorithms to analyze market data and make trading decisions in fractions of a second, often capitalizing on small price discrepancies or market inefficiencies.
"Substring indices" typically refers to the positions or indices of characters within a substring of a string. In programming, substrings are segments of a larger string, and indices usually refer to the numerical positions of characters within that string. ### In the Context of Programming Languages 1. **Indexing starts at 0**: Most programming languages (like Python, Java, C++, etc.
Albert F. A. L. Jones is not a widely recognized name in public discourse or historical records up to October 2023. It's possible that he may be a lesser-known figure or that you're referring to someone specific in a certain field or context. If you have additional details or context about who Albert F. A. L.
Francis Charles McMath is the name of an American mathematician known for his contributions to various areas of mathematics, although specific details about his work or prominence may vary. Without more context or specific information, it's difficult to provide a precise answer.
"John Broughton" can refer to different subjects depending on the context. Here are a few possibilities: 1. **Historical Figure**: John Broughton (c. 1700–1789) was a notable British bare-knuckle boxer and one of the early champions of the sport in the 18th century, known for his contributions to the development of boxing rules.
Otto Kippes is not a widely recognized name or term, and there may not be readily available information related to it. It's possible that Otto Kippes could refer to a specific individual, business, or concept not well-documented in widespread sources.

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.
