On approximation of topological groups by finite algebraic systems. II
arXiv:math/0304065
Abstract
Recall that a locally compact group G is called unimodular if the left Haar measure on G is equal to the right one. It is proved in this paper that G is unimodular iff it is approximable by finite quasigroups (Latin squares).
