Stability and H\"older regularity of solutions to complex Monge-Amp\`ere equations on compact Hermitian manifolds

Let $(X,\omega )$ be a compact Hermitian manifold. We establish a stability result for solutions to complex Monge-Amp`ere equations with right-hand side in $L^p$, $p>1$. Using this we prove that the solutions are H"older continuous with the same exponent as in the K"ahler case \cite{DDGKPZ14}. Our techniques also apply to the setting of big cohomology classes on compact K"ahler manifolds.
