The characteristic function of rough Heston models

O El Euch, M Rosenbaum - Mathematical Finance, 2019 - Wiley Online Library
It has been recently shown that rough volatility models, where the volatility is driven by a
fractional Brownian motion with small Hurst parameter, provide very relevant dynamics in …
