报告摘要  Abstract

Symplectic induction $\mathrm{Ind}_H^G$ is a construction
of Kazhdan, Kostant and Sternberg producing Hamiltonian G-spaces
from Hamiltonian H-spaces. Guillemin and Sternberg used it to give
a ?Mackey-Wigner? description of Hamiltonian G-spaces whenever G admits
a normal *abelian semidirect factor* N. In this talk, I will describe
how this generalizes to a full ?Mackey? description (and classification)
valid for arbitrary normal subgroups N, and explain why this is best
done in the setting of *prequantum* (contact) G-spaces.
