A Note on some Open Problems in Topological Algebra

ARHANGEL’SKII, A. V. (Technical University of Moldova, 2021)

Objects of topological algebra, defined as a certain combination of algebraic and topological structures, often give rise to original and unusual questions. A special additional topological property of many topological ...
On the semigroup of endomorphisms of a topological universal algebra

CHOBAN, Mitrofan; VALUŢĂ, Ion (Technical University of Moldova, 2021)

A topological Ω-algebra or a topological universal algebra of the signature Ω is a family {GenG: n e N} where G is a non-empty topological space and enG: Ωn×Gn → G is a continuous mapping fore each n eω.
