*Abstract***: **Two-sided restriction
semigroups are a class of semigroups which
generalizes both inverse semigroups and
monoids. After
giving a brief introduction into restriction
semigroups and congruences on them, we shall
define the notion of a double partial action
of a restriction semigroup and then use this
concept to obtain a result analogous to O'Carroll's embedding theorem
for inverse semigroups. This is a joint work
in progress with Mikhailo Dokuchaev and Ganna
Kudryavtseva.

Vljudno vabljeni!
