An index of semiotics articles typically refers to a compilation or list of scholarly articles and publications that focus on the study of semiotics, which is the theory and study of signs and symbols, their use and interpretation. This can encompass a wide range of topics, including linguistics, literature, art, communication, culture, and visual studies.
A Hausdorff space, also known as a \(T_2\) space, is a type of topological space that satisfies a particular separation property.
Organisational semiotics is an interdisciplinary approach that studies the use of signs, symbols, and meaning within organizations. It focuses on how communication, representation, and interpretation shape organizational practice and culture. Drawing from semiotics—the study of signs and symbols and their use or interpretation—this framework examines how meaning is constructed and conveyed in organizational contexts.
In algebraic geometry and the broader context of sheaf theory, a **torsion sheaf** is a type of sheaf that is closely related to the concept of torsion elements in algebraic structures. More formally, a torsion sheaf is defined in the context of a sheaf of abelian groups (or modules) associated with a topological space or a scheme. ### Definition 1.
In mathematics and logic, the "sign relation" can refer to several concepts, depending on the context in which it is used. Here are a couple of interpretations: 1. **Sign of a Number**: In basic arithmetic and algebra, the sign of a number indicates whether it is positive, negative, or zero. For example, the sign relation between real numbers can be described as follows: - A number \( x > 0 \) has a positive sign.
Semiotic anthropology is an interdisciplinary field that combines principles of semiotics—the study of signs and symbols and their use or interpretation—with anthropology, which is the study of human societies, cultures, and their development. Essentially, semiotic anthropology examines how meaning is created, shared, and understood within specific cultural contexts.
"Semiotics of the Kitchen" is a video artwork created by artist Martha Rosler in 1975. The work is a critical exploration of the roles and symbols associated with domesticity and femininity, particularly in the context of the 1970s. In the piece, Rosler performs a series of actions involving kitchen utensils and appliances, presenting them in a manner reminiscent of a cooking show or tutorial.
A Leray cover is a concept from algebraic topology, particularly in the context of sheaf theory and inclusion of singularities in topological spaces. Given a space \( X \), a Leray cover is a specific type of open cover that satisfies certain properties, used primarily for the purposes of computing sheaf cohomology.
"The Message in the Bottle" is a phrase that commonly refers to a romantic or poetic notion of sending a message via a bottle thrown into the sea, symbolizing communication across distances and the hope of connection with others. The concept has been used in literature, film, and art to express themes of isolation, longing, and the search for meaning or companionship.
Belgian aircraft registration marks are typically prefixed with "OO" followed by a series of letters that identify the specific aircraft. For example, a Belgian registered aircraft might have a registration like "OO-ABC." The "OO" prefix is assigned to Belgium by the International Civil Aviation Organization (ICAO). As for aircraft serial numbers, these are unique identifiers assigned by the manufacturer to each individual aircraft.
An Internment Serial Number (ISN) typically refers to a unique identifier assigned to individuals who are detained or interned, often in the context of wartime or national security concerns. This term may be particularly associated with the internment of Japanese Americans during World War II, where internees were assigned serial numbers for identification purposes. In a broader context, ISNs can be used in various types of internment facilities or detention centers to keep track of individuals and their records.
A serial number is a unique identifier assigned to an individual item or product. It is typically used to distinguish that item from others of the same type, allowing for tracking and identification across various systems and processes. Serial numbers can be found on a wide range of items, including electronics, appliances, vehicles, and software. The purpose of a serial number includes: 1. **Identification**: Helps manufacturers, retailers, and consumers identify specific products.
The Larner–Johnson valve is a type of medical valve used in the field of cardiology, specifically in procedures involving the heart. It is designed to help control blood flow within the cardiovascular system, particularly in patients with congenital heart defects or other heart conditions that may require surgical intervention. The valve is known for its unique design that allows it to function effectively in a variety of clinical situations.
Azriel Lévy is a Jewish name that might refer to individuals in various contexts, but it does not specifically point to a widely known historical figure, event, or concept based on the information available up to October 2023.
Donald A. Martin is a prominent mathematician known for his work in set theory, particularly in the areas concerning forcing, large cardinals, and the foundations of mathematics. He has contributed significantly to the understanding of models of set theory and their properties. If you were looking for information about a different Donald A.
As of my last knowledge update in October 2021, Eric Charles Milner is not a widely recognized public figure, and there may not be significant available information on him. It's possible that he could be an author, academic, or professional in a specific field.
Harvey Friedman is a well-known mathematician, particularly recognized for his work in mathematical logic, set theory, and the foundations of mathematics. He has made significant contributions to topics such as reverse mathematics, large cardinals, and the philosophy of mathematics. Friedman's research often explores the relationships between various mathematical theories and the complexities involved in formal proofs. In addition to his theoretical work, he is also known for his engagement with the mathematical community, including teaching and mentoring students.
Lyudmila Keldysh is a name associated with several notable figures, most prominently with the Russian mathematician and physicist Lyudmila Keldysh (or Lyudmila Keldysh-Udivanova). She is known for her contributions to various fields in mathematics and physics, particularly in the areas of approximation theory and mathematical physics.
In mathematics, particularly in set theory, a **reflecting cardinal** is a type of large cardinal. A cardinal number \( \kappa \) is considered a reflecting cardinal if it has the property that every property that can be expressed in the language of set theory that is true for all larger cardinals is also true for \( \kappa \) itself, provided that the property holds for some set of size greater than \( \kappa \).
Robert M. Solovay is an American mathematician known for his contributions to set theory, logic, and mathematical foundations. He was born on March 22, 1938. Solovay is particularly recognized for his work on forcing and the independence of certain propositions from the standard axioms of set theory, such as the Continuum Hypothesis. He has made significant contributions to the understanding of large cardinals and their relationships with other set-theoretic concepts.

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.
