The spectrum of positive elliptic operators and periodic bicharacteristics
Let X be a compact boundaryless C ∞ manifold and let P be a positive elliptic self-adjoint pseudodifferential operator of order m>0 on X. For technical reasons we will assume that P operates on
Geometric quantization and multiplicities of group representations
The Heisenberg uncertainty principle says that it is impossible to determine simultaneously the position and momentum of a quantum-mechanical particle. This can be rephrased as follows: the smallest
Convexity properties of the moment mapping. II
