Title: Some recent results on (asymptotics of) rough volatility models
Abstract: Following recent works by Bayer-Friz-Gatheral-Rosenbaum…, we shall consider the small-time behaviour of some fractional volatility models. Absence of Markovianity rules out classical PDE methods, but probabilistic tools such as large deviations apply to these Gaussian models. We will in particular focus on the following aspect: Asymptotic expansions of densities of rough volatility models.
This is based on joint works with Philipp Harms, Blanka Horvath, Mikko Pakkanen and Henry Stone.
