Stochastic Persistence in Infinite Dimensions
Juraj Foldes, Declan Stacy
Motivated by infinite-dimensional ecological and biological models such as reaction-diffusion SPDEs and stochastic functional differential equations, we develop a general criteria…
Small-time asymptotics for hypoelliptic diffusions
Juraj Földes, David P. Herzog
An inductive procedure is developed to calculate the asymptotic behavior at time zero of a diffusion with polynomial drift and degenerate, additive noise. The procedure gives rise…
Probabilistic well-posedness of generalized cubic nonlinear Schrödinger equations with strong dispersion using higher order expansions
Jean-baptiste Casteras, Juraj Földes, Itamar Oliveira +1
In this paper, we study the local well-posedness of the cubic Schrödinger equation …
Singular radial solutions for the Keller-Segel equation in high dimension
Denis Bonheure, Jean-Baptiste Casteras, Juraj Foldes
We study singular radially symmetric solution of the stationary Keller-Segel equation, that is, an elliptic equation with exponential nonlinearity, which is super-critical in dimen…
On higher integrability estimates for elliptic equations with singular coefficients
Juraj Földes, Tuoc Phan
In this note we establish existence and uniqueness of weak solutions of linear elliptic equation , where the matrix…
