Dynamical systems | Cohomology theories | Algebraic topology
In mathematics a cocycle is a closed cochain. Cocycles are used in algebraic topology to express obstructions (for example, to integrating a differential equation on a closed manifold). They are likewise used in group cohomology. In autonomous dynamical systems, cocycles are used to describe particular kinds of map, as in the Oseledets theorem. (Wikipedia).

What is a Coordinate Covalent Bond?
This chemistry video tutorial provides a basic introduction into coordinate covalent bond. Line any covalent bond, electrons are shared. However, in a coordinate covalent bond, one atom donates both electrons that contribute to the formation of the bond. A lewis acid lewis base reaction

Twisted Cocycles = (Vector Bundles + Sections of Vector Bundles)
A Trick: If J is a torsor under a vector bundle T then it turns out that the class of J in H^1(X,T) actually correspond to a class in H^1(X, GG^r_a \rtimes GL_r). This is part 1 of 2 of some videos that explain this. Here we just show how to convert cocycle. The second part we introduce th
