Abstract

In this paper, we consider slow-fast McKean–Vlasov stochastic differential equations driven by fractional Brownian motions with Hurst parameter [Formula: see text] and Brownian motions. We give a definition of the large deviation principle (LDP) on the product space related to fractional Brownian mo...
