  In this paper we develop a method to solve evolution equations on Gelfand
triples with time-fractional derivative based on monotonicity techniques.
Applications include deterministic and stochastic quasi-linear partial
differential equations with time-fractional derivatives, including
time-fractional (stochastic) porous media equations (including the case where
the Laplace operator is also fractional) and $p$-Laplace equations as special
cases.
