Weak Existence and Uniqueness for McKean-Vlasov SDEs with Common Noise
William R. P. Hammersley, David Šiška, Łukasz Szpruch
This paper concerns the McKean-Vlasov stochastic differential equation (SDE) with common noise. An appropriate definition of a weak solution to such an equation is developed. The i…

McKean-Vlasov SDEs under Measure Dependent Lyapunov Conditions
William Hammersley, David Šiška, Lukasz Szpruch
We prove the existence of weak solutions to McKean-Vlasov SDEs defined on a domain with continuous and unbounded coefficients that satisfy Lyapunov type…
