Tanaka formula for SDEs driven by fractional Brownian motion
Tommi Sottinen, Ercan Sönmez, Lauri Viitasaari
We derive a Tanaka-type formula for the solution of a stochastic differential equation (SDE) driven by fractional Brownian motion (fBm) with Hurst parameter . Whil…

Gaussian-type density estimates for mixed SDEs driven by correlated fractional Brownian motions
Maximilian Buthenhoff, Ercan Sönmez
In this work, we investigate the existence and properties of Gaussian-like densities for weak solutions of multidimensional stochastic differential equations driven by a mixture of…

Strong solutions for singular SDEs driven by long-range dependent fractional Brownian motion and other Volterra processes
Maximilian Buthenhoff, Ercan Sönmez
We investigate the well-posedness of stochastic differential equations driven by fractional Brownian motion, focusing on the long-range dependent case . Whi…
