Sensitivity Analysis with respect to a Stock Price Model with Rough Volatility via a Bismut-Elworthy-Li Formula for Singular SDEs
Emmanuel Coffie, Sindre Duedahl, Frank Proske
In this paper, we show the existence of unique Malliavin differentiable solutions to SDE`s driven by a fractional Brownian motion with Hurst parameter H<1/2 and singular, unbounded…

Thiele's Differential Equation Based on Markov Jump Processes with Non-countable State Space
Emmanuel Coffie, Sindre Duedahl, Frank Proske
In modern life insurance, Markov processes in continuous time on a finite or at least countable state space have been over the years an important tool for the modelling of the stat…

Construction of Malliavin differentiable strong solutions of SDEs under an integrability condition on the drift without the Yamada-Watanabe principle
David R. Baños, Sindre Duedahl, Thilo Meyer-Brandis +1
In this paper we aim at employing a compactness criterion of Da Prato, Malliavin, Nualart for square integrable Brownian functionals to construct unique strong solutions of SDE's u…
