Gelfand-Fuchs cohomology of invariant formal vector fields
Ilya Shapiro, Xiang Tang
Let be a finite group acting linearly on a vector space . We compute the Lie algebra cohomology of the Lie algebra of -invariant formal vector fields on . We use this…
Noncommutative Poisson structures on Orbifolds
Gilles Halbout, Xiang Tang
In this paper, we compute the Gerstenhaber bracket on the Hoch-schild cohomology of for a finite group acting on a compact manifold . Using this compu…
Hopfish structure and modules over irrational rotation algebras
Christian Blohmann, Xiang Tang, Alan Weinstein
Inspired by the group structure on , we introduce a weak hopfish structure on an irrational rotation algebra of finite Fourier series. We consider a class of simple…
Poisson geometry and deformation quantization near a pseudoconvex boundary
Eric Leichtnam, Xiang Tang, Alan Weinstein
Let X be a complex manifold with strongly pseudoconvex boundary M. If u is a defining function for M, then -log u is plurisubharmonic on a neighborhood of M in X, and the (real) 2-…
