Title: Pfaffian equation with constraints

Abstract: We discuss some formal theory of over-determined systems of partial differential equations; the involutivity and the integrability by means of prolongation of constrained Pfaffian systems. Then we prove a generalization of the Frobenius theorem. As possible applications we present several open problems that arise from complex analysis, differential geometry and control theory.

Title: Homogeneous Siegel domain

Abstract: Every bounded homogeneous domain in the Euclidean space can be realized as a homogeneous Siegel domain of the second kind. These domains are intensively studied by Piatetskii-Shapiro, Gindikin, Dorfmeister, D'Atri and other mathematicians from 1960's to 1980's. In this series talk I will present basic properties of homogeneous Siegel domains and Lie algebra structures of the automorphism groups.
