Continuity of solutions to complex Monge-Amp\`{e}re equations on compact K\"{a}hler spaces

Summary:We prove the continuity of bounded solutions to complex Monge-Amp\`{e}re equations on reduced, locally irreducible compact K\"{a}hler spaces. This in particular implies that any singular K\"{a}hler-Einstein potentials constructed in \cite{EGZ09} and \cite{Tsuji88, TianZhang06, ST17} are continuous. We also provide an affirmative answer to a conjecture in \cite{EGZ09} by showing that a resolution of any compact normal K\"{a}hler space satisfies the continuous approximation property. Finally, we settle the continuity of the potentials of the weak K\"{a}hler-Ricci flows \cite{ST17, GLZ20} on compact K\"{a}hler varieties with log terminal singularities.
