Category theory

Permutation category

In mathematics, the permutation category is a category where 1. * an object is a natural number, 2. * a morphism is an element of the symmetric group when and is none otherwise. It is equivalent as an category to the category of finite sets and bijections between them. (Wikipedia).

Permutation Groups and Symmetric Groups | Abstract Algebra

We introduce permutation groups and symmetric groups. We cover some permutation notation, composition of permutations, composition of functions in general, and prove that the permutations of a set make a group (with certain details omitted). #abstractalgebra #grouptheory We will see the

301.5C Definition and "Stack Notation" for Permutations

What are permutations? They're *bijective functions* from a finite set to itself. They form a group under function composition, and we use "stack notation" to denote them in this video.

Angélica M. Osorno - Equivariant Infinite Loop Space Machines

An equivariant infinite loop space machine is a functor that constructs genuine equivariant spectra out of simpler categorical or space level data. In the late 80’s Lewis–May–Steinberger and Shimakawa developed generalizations of the operadic approach and the G-space approach respectively.
