Lie-Gruppen und Lie-Algebren
Dieses Buch versteht sich als Einfuhrung in die Theorie der Lie-Gruppen. Der Begriff der Lie-Gruppen wird ausgehend von den einfachsten Beispielen, den Matrizengruppen, entwickelt. Eine grosse AnzahlExpand

Basic Lie Theory
This chapter is devoted to the subject proper of this book: Lie groups, defined as smooth manifolds with a group structure such that all structure maps (multiplication and inversion) are smooth. HereExpand

A Lewis Correspondence for submodular groups
Abstract We extend the Lewis Correspondence between Maaß wave forms and period functions to subgroups of the modular group of finite index. The period functions then become vector valued functions.

Contraction of Hamiltonian $K$-spaces
In the spirit of recent work of Harada-Kaveh and Nishinou-Nohara-Ueda, we study the symplectic geometry of Popov's horospherical degenerations of complex algebraic varieties with the action of aExpand
