Stochastic differential equations driven by fractional Brownian motion with locally Lipschitz drift and their implicit Euler approximation

SQ Zhang, C Yuan - Proceedings of the Royal Society of Edinburgh …, 2021 - cambridge.org
In this paper, we study a class of one-dimensional stochastic differential equations driven by
fractional Brownian motion with Hurst parameter. The drift term of the equation is locally …

which allows forecasting interest rates from observed financial market data even when rates …

Standard and fractional reflected Ornstein–Uhlenbeck processes as the limits of square roots of Cox–Ingersoll–Ross processes

Y Mishura, A Yurchenko-Tytarenko - Stochastics, 2023 - Taylor & Francis
In this paper, we establish a new connection between Cox–Ingersoll–Ross (CIR) and
reflected Ornstein–Uhlenbeck (ROU) models driven by either a standard Wiener process or …

On the ergodicity of a three-factor CIR model

G Ascione, M Bufalo, G Orlando - arXiv preprint arXiv:2307.11443, 2023 - arxiv.org
This work illustrates a tri-factor model referred to as the $ CIR^ 3$ model, where both the
trend and the volatility are stochastic and correlated. For the said model we prove that a …

Positive solutions of the fractional SDEs with non-Lipschitz diffusion coefficient

K Kubilius, A Medžiūnas - Mathematics, 2020 - mdpi.com
We study a class of fractional stochastic differential equations (FSDEs) with coefficients that
may not satisfy the linear growth condition and non-Lipschitz diffusion coefficient. Using the …
