چکیده
In this paper, we study the blow-up of solution to a semilinear time–space fractional diffusion equation, where time derivative is Caputo–type with exponential kernel (“the Caputo derivative” for brevity) order $$\alpha \in (0,1)$$ and spatial Laplacian $$s\in (0, 1)$$ . We first define mild considered equation in terms convolution form, fundamental solutions are denoted by Fox H-functions. The local existence uniqueness further obtained using fixed point argument. Then, weak defined test function it proved be solution. Finally, finite shown. Besides, global shown too critical index determined.
