Representation theory

Tilting theory

In mathematics, specifically representation theory, tilting theory describes a way to relate the module categories of two algebras using so-called tilting modules and associated tilting functors. Here, the second algebra is the endomorphism algebra of a tilting module over the first algebra. Tilting theory was motivated by the introduction of reflection functors by Joseph Bernšteĭn, Israel Gelfand, and V. A. Ponomarev; these functors were used to relate representations of two quivers. These functors were reformulated by Maurice Auslander, , and Idun Reiten, and generalized by Sheila Brenner and Michael C. R. Butler who introduced tilting functors. Dieter Happel and Claus Michael Ringel defined tilted algebras and tilting modules as further generalizations of this. (Wikipedia).

Dynamics : An overview of the cause of mechanics

Dynamics is a subset of mechanics, which is the study of motion. Whereas kinetics studies that motion itself, dynamics is concerned about the CAUSES of motion. In particular, it involves the concepts of force, momentum and energy. This video gives an overview of what dynamics is, and is u
