Rough volatility, path-dependent PDEs and weak rates of convergence

O Bonesini, A Jacquier, A Pannier - arXiv preprint arXiv:2304.03042, 2023 - arxiv.org
In the setting of stochastic Volterra equations, and in particular rough volatility models, we
show that conditional expectations are the unique classical solutions to path-dependent …

Random neural networks for rough volatility

A Jacquier, Z Zuric - arXiv preprint arXiv:2305.01035, 2023 - arxiv.org
We construct a deep learning-based numerical algorithm to solve path-dependent partial
differential equations arising in the context of rough volatility. Our approach is based on …

Numerical approximation of SDEs with fractional noise and distributional drift

L Goudenège, EM Haress, A Richard - Stochastic Processes and their …, 2025 - Elsevier
We study the numerical approximation of SDEs with singular drifts (including distributions)
driven by a fractional Brownian motion. Under the Catellier–Gubinelli condition that imposes …

Local volatility under rough volatility

F Bourgey, S De Marco, PK Friz… - Mathematical Finance, 2023 - Wiley Online Library
Several asymptotic results for the implied volatility generated by a rough volatility model
have been obtained in recent years (notably in the small‐maturity regime), providing a better …

Euler scheme for SDEs driven by fractional Brownian motions: integrability and convergence in law

J León, Y Liu, S Tindel - arXiv preprint arXiv:2307.06759, 2023 - arxiv.org
In this note we consider stochastic differential equations driven by fractional Brownian
motions (fBm) with Hurst parameter $ H> 1/3$. We prove that the corresponding modified …

Weak Error Rates for Numerical Schemes of Nonsingular Stochastic Volterra Equations with Application to Stochastic Volatility Models

P Bras, M Fukasawa - SIAM Journal on Financial Mathematics, 2025 - SIAM
We study the weak error rate for the Euler–Maruyama scheme for stochastic Volterra
equations (SVEs) with application to pricing under stochastic volatility models. SVEs are non …

Functional quantization of rough volatility and applications to the VIX

O Bonesini, G Callegaro, AJ Jacquier - Available at SSRN …, 2021 - papers.ssrn.com
We develop a product functional quantization of rough volatility. Since the quantizers can be
computed offline, this new technique, built on the insightful works by Luschgy and Pages …

Weak error rates for option pricing under linear rough volatility

C Bayer, EJ Hall, R Tempone - International Journal of Theoretical …, 2022 - World Scientific
In quantitative finance, modeling the volatility structure of underlying assets is vital to pricing
options. Rough stochastic volatility models, such as the rough Bergomi model [C. Bayer, PK …
