 題目："Symplectic geometry of the moduli space of hyperbolic 0-metrics"

ABSTRACT: A hyperbolic 0-metric on a compact surface with boundary is a
hyperbolic metric on the interior, with a boundary behaviour similar to
that of the Poincare metric on the upper half plane. The
infinite-dimensional Teichmueller space of such metrics is defined as the
quotient by the identity component of diffeomorphisms fixing the boundary.
We show that these spaces have natural symplectic structures, and are
examples of Hamiltonian Virasoro spaces. Based on joint work with Anton
Alekseev

皆様のご参加をお待ち申し上げます。
