A non-local singular non-linear Fokker-Planck PDE

Luca Bondi, Elena Issoglio, Francesco Russo

The focus of this paper is a non-local singular non-linear Fokker-Planck partial differential equation (PDE). The peculiarity of this PDE feature is in its divergence coefficient,…

McKean-Vlasov equations with singular coefficients - a review of recent results

Luca Bondi, Elena Issoglio, Francesco Russo

This paper focuses on recent works on McKean-Vlasov stochastic differential equations (SDEs) involving singular coefficients. After recalling the classical framework, we review exi…

-It{ô} chain rules and generalized solutions of parabolic PDEs

Carlo Ciccarella, Francesco Russo

In this paper we first establish an Itô formula for a finite quadratic variation process expanding when is of class in space and is absolutely continuous…

Characteristics and It{ô}'s formula for weak Dirichlet processes: an equivalence result

Elena Bandini, Francesco Russo

The main objective consists in generalizing a well-known It{ô} formula of J. Jacod and A. Shiryaev: given a c{à}dl{à}g process S, there is an equivalence between the fact that S is…

Estimation of the lifetime distribution from fluctuations in Bellman-Harris processes

Jules Olayé, Hala Bouzidi, Andrey Aristov +4

The growth of a population is often modeled as branching process where each individual at the end of its life is replaced by a certain number of offspring. An example of these bran…

The -norm of the forward stochastic integral w.r.t. Fractional Brownian motion

Alberto Ohashi, Francesco Russo

In this article, we present the exact expression of the -norm of the forward stochastic integral driven by the multi-dimensional fractional Brownian motion with parameter $\fr…
