Matroid theory is a branch of combinatorial mathematics that generalizes the notion of linear independence in vector spaces. A matroid is a structure that captures the idea of independence in a more abstract setting, allowing for the study of combinatorial properties of sets and the relationships between them.
Frank–Van der Merwe growth refers to a model of crystal growth, specifically describing the process of how materials grow in a layered fashion, especially in the context of thin films and semiconductor crystals. This growth mode is named after the researchers who contributed to its development, Frank and Van der Merwe. In this model, the growth of the film occurs through a process called "layer-by-layer" growth, or more specifically, "two-dimensional nucleation.
Non-equilibrium thermodynamics is a branch of thermodynamics that deals with systems that are not in thermodynamic equilibrium. While classical thermodynamics primarily focuses on systems at equilibrium where macroscopic properties are well-defined and stable, many real-world processes occur far from equilibrium, involving gradients in temperature, pressure, concentration, or other thermodynamic variables.
Women physicists are female scientists who specialize in the field of physics, which is the study of matter, energy, and the fundamental forces of nature. Throughout history, women have made significant contributions to various areas of physics, such as theoretical physics, astrophysics, condensed matter physics, and particle physics, among others. The involvement of women in physics has often been underrepresented in the past due to various social, cultural, and institutional barriers.
Abstract algebra is a branch of mathematics that studies algebraic structures, which are sets equipped with operations that satisfy certain axioms. The main algebraic structures studied in abstract algebra include: 1. **Groups**: A group is a set equipped with a single binary operation that satisfies four properties: closure, associativity, the existence of an identity element, and the existence of inverses. Groups can be finite or infinite and are foundational in many areas of mathematics.
Abstraction in mathematics refers to the process of extracting the underlying principles or structures from specific examples or particular cases. It involves generalizing concepts and removing unnecessary details to create a broader understanding that can be applied across various contexts. Here are a few key aspects of mathematical abstraction: 1. **Generalization**: Abstraction allows mathematicians to formulate general laws or theories that apply to a wide range of specific cases.
Algebraic combinatorics is a branch of mathematics that combines techniques from algebra, specifically linear algebra and abstract algebra, with combinatorial methods to solve problems related to discrete structures, counting, and arrangements. This area of study often involves the interplay between combinatorial objects (like graphs, permutations, and sets) and algebraic structures (like groups, rings, and fields).
In the context of Wikipedia, a "stub" is a short and incomplete article that provides only basic information on a topic. It indicates that the entry could be expanded with more content. An "algebra stub," specifically, would refer to a Wikipedia article related to algebra that is not fully developed. This could include topics such as algebraic concepts, the history of algebra, notable mathematicians in the field, or applications of algebra in various areas.
Mathematical examples can encompass a wide range of concepts, theories, and calculations across different branches of mathematics. Below are various examples across different areas: ### Arithmetic 1. **Addition**: \[ 7 + 5 = 12 \] 2. **Subtraction**: \[ 15 - 4 = 11 \] 3.
Mathematical projects refer to structured activities or research endeavors focused on exploring and solving mathematical problems, concepts, or theories. These projects can vary widely in scope, complexity, and subject matter, and they can be undertaken by individuals, students, or research teams. Here are some key characteristics and components of mathematical projects: ### Characteristics: 1. **Exploratory Nature**: Many mathematical projects involve exploring new concepts, methods, or applications.

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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
