Abstract

In this paper, we consider the knot complement problem for not null-homologous knots in homology lens spaces. Let MM be a homology lens space with H1(M;Z)ZpH_1(M; \mathbb{Z}) \cong \mathbb{Z}_p and KK a not null-homologous knot in MM. We show that KK is determined by its complement if MM is non-hyperbolic, KK is hyperbolic, and pp is a prime more than 7, or, if MM is actually a lens space L(p,q)L(p,q) and KK represents a generator of H1(L(p,q))H_1(L(p,q)).
