Differential equations driven by fractional Brownian motion. (English) Zbl 1018.60057
The authors consider stochastic differential equations driven by a fractional Brownian motion with Hurst parameter \(H>1/2\), where stochastic integrals are defined pathwise in the Riemann-Stieltjes sense. They present a global existence and uniqueness result for the solutions of such stochastic differential equations in the multidimensional case, with time-dependent coefficients satisfying Lipschitz and Hölder assumptions. The proof relies on an existence and uniqueness theorem for deterministic differential equations, which is based on a contraction principle in Hölder and Besov norms.
