The proofs rely on the fixed point principle to prove the existence of a local solution, then on Kaplan's method to determine sufficient conditions to prove the globel existence, as well as sufficient conditions to prove the non-existence (blow-up ) of solutions.enCaputo fractional derivative; Reaction-diffusion equation; Global solutionGlobal existence and blow-up of solution for some fractional reaction- diffusion problemsOther
