Decomposition of semi-continuous functions into the sum of quasi-continuous functions and the oscillation of almost continuous functions (in Ukrainian) [PDF]
Математичні Студії, 2011 We prove that every semi-continuous function on a metrizable space is decompose into sum of two quasi-continuous functions. And then we obtain a new characterization of the oscillation of almost continuous functions.

Strongly $\sigma$-metrizable spaces are super $\sigma$-metrizable
, 2016 A topological space $X$ is called strongly $\sigma$-metrizable if $X=\bigcup_{n\in\omega}X_n$ for an increasing sequence $(X_n)_{n\in\omega}$ of closed metrizable subspaces such that every convergence sequence in $X$ is contained in some $X_n$. If, in addition, every compact subset of $X$ is contained in some $X_n$, $n\in\omega$, then $X$ is called ...

Topology and its Applications, 1998 The author shows that quasi-(pseudo)metrizability of a topological space \(X\) is equivalent to the availability on \(X\) of a decreasing neighborhood base \((g(n,x))_{n\in \omega}\) at every \(x\in X\) such that for every countable and relatively locally finite \(A\subseteq X\) and \(n\in \omega\) we have \(g(\nu,g(\nu,A))\subseteq g(n,A)\) for some \(

Regular extension operators for partial fuzzy (pseudo)metrics [PDF]
Математичні Студії, 2011 Using the fuzzy modification of the Prokhorov metric on the set of probability measures we prove the theorem on existence of simultaneous extensions of partial fuzzy metrics (for the Lukasiewicz t-norm) defined on closed subsets of a compact metrizable ...

On a lower continuity of upper continuous mappings with values in the Sorgenfrey line(in Ukrainian)
Математичні Студії, 2013 We shown that for each lower continuous finite valued mapping from metrizable topological space $X$ inSorgenfrey line the set of points of upper continuous is residual in $X$.
