On generalized Namioka spaces and joint continuity of functions on product of spaces
Xiongping Dai, Congying Lv, Yuxuan Xie
A space is called a generalized Namioka space (g-space), if for every compact space and every separately continuous function $f\colon X\times Y\rightarrow\math…

Characterizations of open and semi-open maps of compact Hausdorff spaces by induced maps
Xiongping Dai, Yuxun Xie
Let be a continuous surjection of compact Hausdorff spaces. By $$f_*\colon\mathfrak{M}(X)\rightarrow\mathfrak{M}(Y),\ μ\mapsto μ\circ f^{-1} \quad{\rm and}…
