ABSTRACT. The Siegel domain plays in several complex variables the role of the upper half plane in the one-dimensional theory. One of its advantages over the unit ball is that the boundary behavior of the Bergman metric is rather transparent in Siegel coordinates; another one is that its boundary has a (noncommutative) group structure and (noncommutative) Fourier analysis can be used; another one is that the derivative with respect to the "vertical" direction encodes much information concerning classical holomorphic spaces. In these seminars we will give an overview of the rich toolbox available when studying function theory over such domain. The first one will be devoted to the Bergman metric and the automorphism group.
