# What the f*** is K-theory?

All I know that K-theory is like something dealing with physics, kinectics, velocity, math, at stuff like that.

In mathematics, K-theory is, firstly, an extraordinary cohomology theory which consists of topological K-theory. It also includes algebraic K-theory. It spans the subjects of algebraic topology, abstract algebra and some areas of application like operator algebras and algebraic geometry. It leads to the construction of families of K-functors, which contain useful but often hard-to-compute information.

In physics, K-theory and in particular twisted K-theory have appeared in Type II string theory where it has been conjectured that they classify D-branes, Ramond-Ramond field strengths and also certain spinors on generalized complex manifolds. For details, see also K-theory (physics).

can you spell out the k word? Kinematics, Kenitics, or K curve, or billions of other things, so rewrite ur question
