The level crossing problem in semi-classical analysis. II. The Hermitian case

Yves Colin de Verdière (2004)

Annales de l’institut Fourier

Similarity:

This paper is the second part of the paper ``The level crossing problem in semi-classical analysis I. The symmetric case''(Annales de l'Institut Fourier in honor of Frédéric Pham). We consider here the case where the dispersion matrix is complex Hermitian.

On the index theorem for symplectic orbifolds

Boris Fedosov, Bert-Wolfang Schulze, Nikolai Tarkhanov (2004)

Annales de l’institut Fourier

Similarity:

We give an explicit construction of the trace on the algebra of quantum observables on a symplectiv orbifold and propose an index formula.
