Mean-field games with rough common noise: the linear-quadratic case
Peter K. Friz, Ioannis Gasteratos, Ulrich Horst +1
Motivated by mean-field games (MFG) with common noise on the one hand and pathwise stochastic control theory on the other, we formulate here a linear-quadratic (LQ) MFG with rough…
On the Onsager-Machlup functional of the -measure
Ioannis Gasteratos, Zachary Selk
We investigate the existence of generalised densities for the measures, in finite volume, through the lens of Onsager-Machlup (OM) functionals. The latter are…
Kolmogorov equations for stochastic Volterra processes with singular kernels
Ioannis Gasteratos, Alexandre Pannier
We associate backward and forward Kolmogorov equations to a class of fully nonlinear Stochastic Volterra Equations (SVEs) with convolution kernels that are singular at the orig…
Large deviations of slow-fast systems driven by fractional Brownian motion
Siragan Gailus, Ioannis Gasteratos
We consider a multiscale system of stochastic differential equations in which the slow component is perturbed by a small fractional Brownian motion with Hurst index and the…
Uniform attraction and exit problems for stochastic damped wave equations
Ioannis Gasteratos, Michael Salins, Konstantinos Spiliopoulos
We consider a class of wave equations with constant damping and polynomial nonlinearities that are perturbed by small, multiplicative, space-time white noise. The equations are def…
