摘要：

We are concerned with the Cauchy problem for the semilinear parabolic equation driven by the mixed local-nonlocal operator L=-Delta+(-Delta)s$\mathcal {L}= -\Delta +(-\Delta)<^>s$, with a power-like source term. We show that the so-called Fujita phenomenon holds, and the critical value is exactly the same as for the fractional Laplacian.
