Large-time behavior of two families of operators related to the fractional Laplacian on certain Riemannian manifolds

Effie Papageorgiou

This note is concerned with two families of operators related to the fractional Laplacian, the first arising from the Caffarelli-Silvestre extension problem and the second from the…

Asymptotic behavior of solutions to the extension problem for the fractional Laplacian on noncompact symmetric spaces

Effie Papageorgiou

This work deals with the extension problem for the fractional Laplacian on Riemannian symmetric spaces $G / K$ of noncompact type and of general rank, which gives rise to a family of…

Pointwise convergence to initial data for some evolution equations on symmetric spaces

Tommaso Bruno, Effie Papageorgiou

Let $L$ be either the Laplace--Beltrami operator, its shift without spectral gap, or the distinguished Laplacian on a symmetric space of noncompact type $X$ of a…

Asymptotics for the infinite Brownian loop on noncompact symmetric spaces

Effie Papageorgiou

The infinite Brownian loop on a Riemannian manifold is the limit in distribution of the Brownian bridge of length $T$ around a fixed origin when $T \to + \infty$ . The aim of…
