The present thesis is devoted to the study of stochastic Volterra processes and their applications to finance. We begin by recalling some properties of these processes that will be used throughout this work. The second part focuses on the study of an optimal stopping problem, namely the problem of pricing American options in the Volterra Heston model. For a particular choice of the parameters, this model is a rough version of the widely-known Heston model. We concentrate on the convergence of the prices in an approximating sequence of high dimensional models towards the prices in the limiting Volterra model. The third part of this work is devoted to the study of the moments for polynomial Volterra processes. We develop some methods for c...
