## Stochastic Volterra equations driven by fractional Brownian motion with Hurst parameter $$H>1/2$$.(English)Zbl 1261.60066

Consider the following stochastic Volterra equation in $$\mathbb{R}^d$$, $X(t) = X_0 + \int_0^t b(t,s,X(s))\,ds + \int_0^t \sigma(t,s,X(s))dW^H_s, \;t \in [0,T],$ where $$W^{H,j}_t$$ for $$j=1,\dotsc,m$$ are independent fractional Brownian motions with Hurst parameter $$H > \frac{1}{2}$$.
In this paper, the authors extend results by D. Nualart and A. Răşcanu [“Differential equations driven by fractional Brownian motion”, Collect. Math. 53, No. 1, 55–81 (2002; Zbl 1018.60057)], to multidimensional stochastic Volterra equations. Using the Riemann-Stieltjes integral, they give the existence and uniqueness of a solution to the above equation. They also show that the solution has finite moments. Their main aim is to obtain precise estimates for Lebesgue and Riemann-Stieltjes Volterra integrals.
