The critical exponents for a semilinear fractional pseudo-parabolic equation with nonlinear memory in a bounded domain

This paper considers blow-up and global existence for a semilinear space-time fractional pseudo-parabolic equation with nonlinear memory in a bounded domain. We determine the critical ex-ponents of the Cauchy problem when alpha < gamma and alpha >= gamma, respectively. The results obtained in this study are noteworthy extension to the results of time-fractional differential equation. The critical exponent is consistent with the corresponding Cauchy problem for the time-fractional differential equation with nonlinear memory, which illustrates that the diffusion effect of the third order term is not strong enough to change the critical exponents.
