### Peter Woit on BRST cohomology

Peter Woit, the author of the blog Not Even Wrong, is writing a series of articles about BRST cohomology and Lie algebra cohomology, as pointed out by the Secret Blogging seminar. Since these theories are now fundamental in the study of gauge symmetry in quantum mechanics and Lie group actions on differentiable manifolds (these subjects now being often blended into each other), having a nice introduction written as blog posts is undoubtedly useful !
