What is Viability theory?

In mathematics, specifically in homotopy theory and category theory, coherency is the standard that equalities or diagrams must satisfy when they hold "up to homotopy" or "up to isomorphism". The...

The IEEE International Symposium on Information Theory is the flagship meeting of the IEEE Information Theory Society. Every year and during the course of a week, researchers in the field...

The Iran Workshop on Communication and Information Theory is an international academic workshop that is held annually in one of the Iranian University campuses. The purpose of this workshop...

Propeller theory is the science governing the design of efficient propellers. A propeller is the most common propulsor on ships, and on small aircraft.

In category theory, a branch of mathematics, a pullback is the limit of a diagram consisting of two morphisms f : X → Z and g : Y → Z with a common codomain. The pullback is...

In ring theory, a branch of abstract algebra, an idempotent element or simply idempotent of a ring is an element a such that a = a. That is, the element...

In mathematical logic, and more specifically in model theory, an infinite structure which is totally ordered by < is called an o-minimal structure if and only if every definable subset...

In mathematics, the Double extension set theory is an axiomatic set theory proposed by Andrzej Kisielewicz consisting of two separate membership relations on the universe of sets, denoted here by...

Many first principles in quantum field theory are explained, or get further insight, in string theory.
