In the first chapter, the large time behavior of non-negative solutions to the reaction-diffusion equation $\partial_t u=-(-\Delta)^{\alpha/2}u - u^p,$ $(\alpha\in(0,2], \;p>1)$ posed on $\mathbb{R}^N$ and supplemented with an integrable initial condition is studied. We show that the anomalous diffusion term determines the large time asymptotics for $p>1+{\alpha}/{N},$ while nonlinear effects win if $p\leq1+{\alpha}/{N}.$\\ In chapter two, we present first a new technique to prove, in a general case, the recent result of Cazenave, Dickstein and Weissler on the blowing-up solutions to a temporally nonlocal nonlinear parabolic equation.\\ Then, we study the blow-up rate and the global existence in time of the solutions. Furthermore, we establ...
