Large deviation principle for multi-scale distribution dependent stochastic differential equations driven by fractional Brownian motions
Abstract
In this paper, we are concerned with multi-scale distribution dependent stochastic differential equations driven by fractional Brownian motion (with Hurst index H>12 and standard Brownian motion, simultaneously. Our aim is to establish a large deviation principle for the multi-scale distribution dependent stochastic differential equations. This is done via the weak convergence approach and our proof is based heavily on the fractional calculus.
