Talks (45 minutes)
- S. Gindikin (Rutgers, USA)
Horospheric geometry of symmetric spaces. (2 talks)
The fundamental project of Gelfand to develop harmonic analysis on symmetric spaces
on the base of the horospherical duality was for a long time realized only for a relatively
narrow class of symetric spaces.
I believe that the union of this approach with complex geometrical analysis makes it universal.
- T. Kobayashi (Tokyo, Japon)
Global Geometry and Analysis on Locally Homogeneous Spaces. (2 talks)
The local to global study of geometries was a major trend of 20th century geometry, with
remarkable developments achieved particularly in Riemannian geometry. In contrast, in
areas such as Lorentz geometry, familiar to us as the space-time of relativity theory,
and more generally in pseudo-Riemannian geometry, surprising little is known about global
properties of the geometry even if we impose a locally homogeneous structure. Further,
almost nothing is known on global analysis on such spaces.
Taking anti-de Sitter manifolds, which are locally modelled on AdS^n as an example, I
plan to explain two programs:
1. (global shape) Is a locally homogeneous space closed?
2. (spectral analysis) Does spectrum of the Laplacian vary when we deform the geometric
structure?
- V. Molchanov (Tambov, Russie)
Complex hulls of the hyperboloid of one sheet and the analytic continuation
of spherical functions. (2 talks)
For the hyperboloid of one sheet in \({\Bbb R}^3\), we construct four
complex hulls and continue analytically to them spherical functions
of different series (continuous (twice), holomorphic and antiholomorphic).
For any of these series, we write the projection operator and the
Cauchy-Szegö kernel.
