A K-Theoretic Note on Geometric Quantization
David S. Metzler
We show that the results of the paper Symplectic Reduction and Riemann-Roch for Circle Actions of Duistermaat, Guillemin, Meinrenken and Wu can be expressed entirely in K-theory. W…

A Wall-crossing Formula for the Signature of Symplectic Quotients
David S. Metzler
We use symplectic cobordism, and the localization result of Ginzburg, Guillemin, and Karshon, to find a wall-crossing formula for the signature of regular symplectic quotients of H…
