Some notes on Pontryagin duality of abelian topological groups

Linus Kramer, Karl Heinrich Hofmann

We consider several questions related to Pontryagin duality in the category of abelian pro-Lie groups.

A short note on coproducts of abelian pro-Lie groups

Wolfgang Herfort, Karl H. Hofmann, Francesco G. Russo

The notion of conditional coproduct of a family of abelian pro-Lie groups in the category of abelian pro-Lie groups is introduced. It is shown that the cartesian product of an arbi…

On Weakly Complete Universal Enveloping Algebras: A Poincare-Birkhoff-Witt Theorem

Karl H. Hofmann, Linus Kramer

We study universal enveloping Hopf algebras of Lie algebras in the category of weakly complete vector spaces over the real and complex field.

On weakly complete group algebras of compact groups

Karl Heinrich Hofmann, Linus Kramer

We study group algebras for compact groups in the category of real and complex weakly complete vector spaces. We also show that the group algebra is a quotient of the weakly comple…

The Pro-Lie Group Aspect of Weakly Complete Algebras and Weakly Complete Group Hopf Algebras

Rafael Dahmen, Karl Heinrich Hofmann

A weakly complete vector space over or is isomorphic to for some set algebraically and topologically. The signifi…

Automatic continuity of abstract homomorphisms between locally compact and Polish groups

Oskar Braun, Karl Heinrich Hofmann, Linus Kramer

We are concerned with questions of the following type. Suppose that and are topological groups belonging to a certain class of spaces, and suppose that …
