- Abstract:
- Let S⊆C*=C{0} and A∈Mn(C). The matrix A is called an S-GHMn if A∈Mn(S) and AA*=Diag(λ1,... λn), for some positive numbers λi, i=1,... n. In this paper we provide some necessary conditions on n for the existence of an S-GHMn over a finite set S. We conjecture that for every positive integer n, there exists a {±1, ±2, ±3}-GHMn
