AUTOMATIC CONTINUITY OF ABSTRACT HOMOMORPHISMS BETWEEN LOCALLY COMPACT AND POLISH GROUPS
We prove results about automatic continuity and openness of abstract surjective group homomorphisms K→φG,\( K\overset{\varphi }{\to }G, \) where G and K belong to a certain class К of topological groups, and wher...
