On approximation of topological groups by finite algebraic systems. II
L. Yu. Glebsky, E. I. Gordon, C. J. Rubio
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 approx…

On approximation of topological groups by finite algebraic systems
L. Yu. Glebsky, E. I. Gordon
It is known that locally compact groups approximable by finite ones are unimodular, but this condition is not sufficient, for example, the simple Lie groups are not approximable by…

The conjecture cr(C_m\times C_n)=(m-2)n is true for all but finitely many n, for each m
Lev Glebsky, Gelasio Salazar
It has been long congectured that the crossing number of is for . In this paper we proved that conjecture is true for all but finitely many for…
