Fuchsian lattices with small trace sets are arithmetic: the noncompact case
Considering a subgroup A of SL(2, R), the trace set of A, Tr(A) is the set of all traces of elements in A. It is known that the trace set of arithmetic lattices in SL(2, R) has linear growth. Shmutz conjectured that the inverse also holds. In this talk, we will give a positive answer to the conjecture in the case of non-uniform lattices.
