Category theory | Group theory
In category theory and homotopy theory the Burnside category of a finite group G is a category whose objects are finite G-sets and whose morphisms are (equivalence classes of) spans of G-equivariant maps. It is a categorification of the Burnside ring of G. (Wikipedia).

Acids and Bases - Short Revision || CBSE Science || || Infinity Learn Class 9&10
Acids and bases are two types of substances that are fundamental to chemistry. An acid is a substance that donates protons (hydrogen ions, H+) to a solution, while a base is a substance that accepts protons or donates hydroxide ions (OH-) to a solution. There are several ways to define and

Types of Silicates Part 2: Inosilicates, Phyllosilicates, and Tectosilicates
In the previous tutorial we learned about some types of silicates, so now let's learn about the rest. That will be inosilicates, phyllosilicates, and tectosilicates. These can get pretty complicated so let's take a closer look! Script by Jared Matteucci and Bryne Hadnott Watch the whole

Mike Hill - Real and Hyperreal Equivariant and Motivic Computations
Foundational work of Hu—Kriz and Dugger showed that for Real spectra, we can often compute as easily as non-equivariantly. The general equivariant slice filtration was developed to show how this philosophy extends from 𝐶2-equivariant homotopy to larger cyclic 2-groups, and this has some fa

Classification of Igneous Rocks: Intrusive vs. Extrusive
