On H1-compositors and piecewise continuous mappings (in Ukrainian)

We introduce the notion of a right $H_1$-compositor and provethat for a hereditarily Baire metrizable space $X$, a normalspace $Y$ and a mapping $fcolon Xo Y$ the followingconditions are equivalent: (i) $f$ is piecewise continuous;(ii) $f$ is $k$-continuous; (iii) $f$ is $G_delta$-measurable;if, mor...
