Abstract

In this paper studied isometries of FF-spaces of integrable functions with logarithm. In particular, using passports of Boolean algebra, a necessary and sufficient condition of isometry FF-spaces of integrable functions of logarithm with respect to strictly positive σ\sigma-finite measures is proved. In this work,external, internal and generalized loglog algebras are considered separately.
