On the density of the supremum of nonlinear SPDEs

Georgia Karali, Alexandra Stavrianidi, Konstantinos Tzirakis +1

We study the one-dimensional stochastic partial differential equation \begin{equation*} \frac{\partial u}{\partial t}(t,x) = -κ\frac{\partial^4 u}{\partial x^4}(t,x) + ρ\frac{\part…

The Fourth-Moment Theorem on Hilbert Spaces

Marie-Christine Düker, Pavlos Zoubouloglou

In this work, we establish conditions ensuring convergence in distribution of a sequence admitting a Wiener-Itô chaos representation to a Gaussian measure on a separable Hilbert sp…

Scaling limits for sample autocovariance operators of Hilbert space-valued linear processes

Marie-Christine Düker, Pavlos Zoubouloglou

This article considers linear processes with values in a separable Hilbert space exhibiting long-range dependence. The scaling limits for the sample autocovariance operators at dif…

Cyclical Long Memory: Decoupling, Modulation, and Modeling

Stefanos Kechagias, Vladas Pipiras, Pavlos Zoubouloglou

A new model for general cyclical long memory is introduced, by means of random modulation of certain bivariate long memory time series. This construction essentially decouples the…

Large Deviations for Empirical Measures of Self-Interacting Markov Chains

Amarjit Budhiraja, Adam Waterbury, Pavlos Zoubouloglou

Let be a finite set and, for each probability measure on , let be a transition probability kernel on . Fix and consider the chain $\{X_n, \…
