Superdiffusive limits for stochastic kinetics driven by self-similar drifts
Miha Brešar, Conrado da Costa, Aleksandar Mijatović +1
We prove anomalous-diffusion scaling for a one-dimensional stochastic kinetic dynamics, in which the stochastic drift is driven by an exogenous self-similar noise, and also include…
Superdiffusive planar random walks with polynomial space-time drifts
Conrado da Costa, Mikhail Menshikov, Vadim Shcherbakov +1
We quantify superdiffusive transience for a two-dimensional random walk in which the vertical coordinate is a martingale and the horizontal coordinate has a positive drift that is…
Limiting distributions for RWCRE in the sub-ballistic regime and in the critical Gaussian regime
Conrado da Costa, Jonathon Peterson, Yongjia Xie
Random Walks in Cooling Random Environments (RWCRE) is a model of random walks in dynamic random environments where the environment is frozen between a fixed sequence of times (cal…
Passage-times for partially-homogeneous reflected random walks on the quadrant
Conrado da Costa, Mikhail Menshikov, Andrew Wade
We consider a random walk on the first quadrant of the square lattice, whose increment law is, roughly speaking, homogeneous along a finite number of half-lines near each of the tw…
Gradual convergence for Langevin dynamics on a degenerate potential
Gerardo Barrera, Conrado da Costa, Milton Jara
In this paper, we study an ordinary differential equation with a degenerate global attractor at the origin, to which we add a white noise with a small parameter that regulates its…
Stochastic billiards with Markovian reflections in generalized parabolic domains
Conrado da Costa, Mikhail V. Menshikov, Andrew R. Wade
We study recurrence and transience for a particle that moves at constant velocity in the interior of an unbounded planar domain, with random reflections at the boundary governed by…
Reaction-diffusion models for a class of infinite-dimensional non-linear stochastic differential equations
Conrado da Costa, Bernardo Freitas Paulo da Costa, Daniel Valesin
We establish the existence of solutions to a class of non-linear stochastic differential equation of reaction-diffusion type in an infinite-dimensional space, with diffusion corres…
