Findings
Established a relative trace map for rigid Stein spaces.
Connected Serre duality on different spaces via the trace map.
Analyzed behavior of Stein spaces under base change and duality relations.
Abstract
We provide a relative version of the trace map from the work of Beyer, which can be associated to any finite tale morphism of smooth rigid Stein spaces and which then relates the Serre duality on with the Serre duality on . Furthermore, we consider the behaviour of any rigid Stein space under (completed) base change to any complete extension field and deduce a commutative diagram relating Serre duality over the base field with the Serre duality over the extension field.
