A pathwise analysis of stochastic evolution equations with locally monotone operators
We establish global existence of weak solutions to stochastic evolution equations on a Gelfand triple with locally monotone operators and sufficiently regular driving signals. Our analysis combines monotone operator theory with recent advances in Besov rough path analysis, requiring no probabilistic structure. This allows treating various operators and signals, including p-Laplace, porous medium, shear-thickening fluids, additive/multiplicative Young integrals, and translated integrals arising in regularization by noise.
