Abstract:
It is proved that every resolvably measurable mapping $f \colon X \rightarrow Y$ of a first-countable perfectly paracompact space $X$ to a regular space $Y$ is piecewise continuous. If $X$ is additionally completely Baire, then $f$ is resolvably measurable if and only if it is piecewise continuous.
Keywords:
resolvably measurable mapping, piecewise continuous mapping, $\mathcal{F}_\sigma$-measurable mapping, completely Baire space.
