Query: Global existence and blow-up for space and time nonlocal
  reaction-diffusion equation   A time-space fractional reaction-diffusion equation in a bounded domain is
considered. Under some conditions on the initial data, we show that solutions
may experience blow-up in a finite time. However, for realistic initial
conditions, solutions are global in time. Moreover, the asymptotic behavior of
bounded solutions is analysed.
