Abstract

Let p be a prime and F be a finite field with q = ps elements. It is well-known that for any nontrivial multiplicative character f of F,

H. Cohn asked whether the converse is true. For the case p is odd and s = 1, A. Biró gives a partial answer to Cohn's problem. In this talk, we give a negative answer to Cohn's problem when q > 4 and s > 1.
