Speaker:

**G/Shevchenko**Title:

**Stochastic differential equations with mixed noise (based on Doctor’s thesis)**The talk will be devoted to so-called “mixed” stochastic differential equations

X(t)=X(0)+0

∫ a(s,X(s))ds+

t0

∫ b(s,X(s))dW(s)+

t0

∫ c(s,X(s))dZ(s),

twhere W is a standard Wiener process, Z is an adapted process trajectories of which almost surely satisfy the Holder condition with constant γ>1/2. Results on existence, uniqueness and integrability of the solution of this equation will be discussed. In case when Z=BH is a fractal Brownian motion with Hurst parameter >1/2 also conditions of Malliavin differentiability and existence of the solution’s density will be given.
