On holomorphic reflexivity conditions for complex Lie groups

Abstract

We consider Akbarov's holomorphic version of the non-commutative Pontryagin duality for a complex Lie group. We prove, under the assumption that GG is a Stein group with finitely many components, that (1) the topological Hopf algebra of holomorphic functions on GG is holomorphically reflexive if and only if GG is linear; (2) the dual cocommutative topological Hopf algebra of exponential analytic functional on GG is holomorphically reflexive. We give a counterexample, which shows that the first criterion cannot be extended to the case of infinitely many components. Nevertheless, we conjecture that, in general, the question can be solved in terms of the Banach-algebra linearity of GG.
