Abstract

The character group ofR is topologically isomorphic toR itself. On the contrary, it is impossible to construct anon-trivial homomorphism from the additive group of the field with characteristicp>0 to the multiplicative group of the field with the same characteristic. In this paper, we construct positive characteristic non-trivial characters and prove self-duality on a certain complete normed divided power algebra.
