Blowup and life span bounds for a reaction-diffusion equation with a time-dependent generator

We consider the nonlinear equation $$ frac{partial}{partial t} u (t) = k (t) Delta _{alpha }u (t) + u^{1+eta } (t),quad u(0,x)=lambda varphi (x),; xin mathbb{R} ^{d}, $$ where $Delta _{alpha }:=-(-Delta)^{alpha /2}$ denotes the fractional power of the Laplacian; $0<alpha leq 2$, $lam...
