Abstract
The authors discuss a long-standing problem of calculating the topological Casimir effect for a massless real scalar field phi on the spacetimes of form R*H3/ Gamma with a discrete group of isometries Gamma of the three-dimensional Lobachevsky space H3 and evaluate the given effect in a generic form for all topologically inequivalent configurations of phi in the case when H3/ Gamma is compact but Gamma contains no elliptic elements. An additional contribution at finite temperature is also deduced.Keywords
