In this thesis, exit-time problem for two types of non-linear diffusion processes is considered. The first process is called the Self-interacting diffusion and is defined by the following SDE including interaction of the process with its own path: d X_t = \sigma d W_t - ( \nabla V(X_t) + \frac{1}{t} \int_0^t \nabla F (X_t - X_s) d s) d t.The second equation of interest is a special case of McKean-Vlasov process that we call the Self-stabilizing diffusion. It is defined by the following SDE including the convolution of the process with its law \Law(X_t): d X_t = \sigma d W_t - ( \nabla V(X_t) + \nabla F*\Law(X_t)(X_t)d s ) d t.By the exit-time problem, we mean the study of the stopping time \tau := \inf\{t \geq 0: X_t \notin G\}, th...
