Abstract:
Maximal linked systems (MLS) and ultrafilters (u/f) on
a widely understood measurable space (this is a nonempty set with
equipment in the form of $\pi$-system with «zero» and «unit»)
are investigated. Under equipment with topology of Wallman type,
the set of MLS is converted into a supercompact $T_1$-space.
Conditions under which given space of MLS is a supercompactum
(i. e., a supercompact $T_2$-space) are investigated. These conditions then apply
to the space of u/f under equipment with topology of Wallman type.
The obtained conditions are coordinated with representations
obtained under degenerate cases of bitopological spaces with
topologies of Wallman and Stone types, but they are not the last to
be exhausted.
Keywords:
maximal linked system, quasineighborhood, topology,
ultrafilter.
