Uniqueness for stochastic differential equations in Hilbert spaces with irregular drift
Lukas Anzeletti, Oleg Butkovsky, Máté Gerencsér +1
We present a versatile framework to study strong existence and uniqueness for stochastic differential equations (SDEs) in Hilbert spaces with irregular drift. We consider an SDE in…

Path-by-path uniqueness for stochastic differential equations under Krylov-Röckner condition
Lukas Anzeletti, Khoa Lê, Chengcheng Ling
We show that any stochastic differential equation (SDE) driven by Brownian motion with drift satisfying the Krylov-Röckner condition has exactly one solution in an ordinary sense…

On the density of singular SDEs with fractional noise and applications to McKean-Vlasov equations
Lukas Anzeletti, Lucio Galeati, Alexandre Richard +1
We investigate properties of the (conditional) law of the solution to SDEs driven by fractional Brownian noise with a singular, possibly distributional, drift. Our results on the l…
