Cohomology theories

Bredon cohomology

The Bredon cohomology, introduced by Glen E. Bredon, is a type of equivariant cohomology that is a contravariant functor from the category of G-complex with equivariant homotopy maps to the category of abelian groups together with the connecting homomorphism satisfying some conditions.

The Completed Cohomology of Arithmetic Groups - Frank Calegari

Frank Calegari Northwestern University; Member, School of Mathematics October 13, 2010 The cohomology of arithmetic groups (with real coefficients) is usually understood in terms of automorphic forms. Such methods, however, fail (at least naively) to capture information about torsion clas

Quantum Electrodynamics (QED)

In our study of physics, we have become aware of four forces, and the fields that mediate them. Once we got deep into quantum theory, we started to realize that these forces are not mediated by fields at all, but rather by quanta. That's why it's called quantum theory, we are showing how p
