Topological semigroups of matrix units
We prove that the semigroup of matrix units is stable. Compact, countably compact and pseudocompact topologies τ on the infinite semigroup of matrix units Bλ such that (Bλ,τ ) is a semitopological (inverse) semigroup are described. We prove the following properties of an infinite topological semi...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | We prove that the semigroup of matrix units is
stable. Compact, countably compact and pseudocompact topologies τ on the infinite semigroup of matrix units Bλ such that (Bλ,τ )
is a semitopological (inverse) semigroup are described. We prove
the following properties of an infinite topological semigroup of matrix units. On the infinite semigroup of matrix units there exists
no semigroup pseudocompact topology. Any continuous homomorphism from the infinite topological semigroup of matrix units into
a compact topological semigroup is annihilating. The semigroup
of matrix units is algebraically h-closed in the class of topological
inverse semigroups. Some H-closed minimal semigroup topologies
on the infinite semigroup of matrix units are considered.
