Query: Decay estimates in time for classical and anomalous diffusion   We present a series of results focused on the decay in time of solutions of
classical and anomalous diffusive equations in a bounded domain. The size of
the solution is measured in a Lebesgue space, and the setting comprises
time-fractional and space-fractional equations and operators of nonlinear type.
We also discuss how fractional operators may affect long-time asymptotics.
