Existence and uniqueness of mild solution to fractional stochastic heat equation

Kostiantyn Ralchenko, Georgiy Shevchenko

For a class of non-autonomous parabolic stochastic partial differential equations defined on a bounded open subset D⊂Rd and driven by an L2(D)-valued fractio…

math.PR2018

Parameter estimation for Gaussian processes with application to the model with two independent fractional Brownian motions

Yuliya Mishura, Kostiantyn Ralchenko, Sergiy Shklyar

The purpose of the article is twofold. Firstly, we review some recent results on the maximum likelihood estimation in the regression model of the form Xt​=θG(t)+Bt​, where $B…

Existence and uniqueness of mild solution to stochastic heat equation with white and fractional noises

Yuliya Mishura, Kostiantyn Ralchenko, Georgiy Shevchenko

We prove the existence and uniqueness of a mild solution for a class of non-autonomous parabolic mixed stochastic partial differential equations defined on a bounded open subset $D…
