Geometrically connected components of Lubin-Tate deformation spaces with level structures
Abstract
Description
Let M_m be the generic fibre of the formal deformation space of a one-dimensional formal module X of finite height together with level-m-structures. We show that it is defined over the mth Lubin-Tate extension of the ground field and that it is geometrically connected over this field. The action of the covering group of M_m over M_0 on the set of geomtrically connected components is calculated as well as the action of the action of the automorphism group of X.
