Abstract

In this paper studied isometries of
F −spaces of integrable functions
with logarithm. In particular, using passports of Boolean algebra, a necessary and
sufficient condition of isometry
F −spaces of integrable functions of logarithm with
respect to strictly positive
 −finite measures is proved.In this work generalized
log− algebras are considered separately.
