New examples of harmonic maps to the hyperbolic plane via Bäcklund transformation
Giannis Polychrou, Effie Papageorgiou, Anestis Fotiadis +1
We study harmonic maps from a subset of the complex plane to a subset of the hyperbolic plane. In \cite{FotDask}, harmonic maps are related to the sinh-Gordon equation and a B{ä}ck…
Asymptotic behavior of solutions to the heat equation on noncompact symmetric spaces
Jean-Philippe Anker, Effie Papageorgiou, Hong-Wei Zhang
This paper is twofold. The first part aims to study the long-time asymptotic behavior of solutions to the heat equation on Riemannian symmetric spaces of noncompact type and…
How many Fourier coefficients are needed?
Benedikt Diederichs, Mihail N. Kolountzakis, Effie Papageorgiou
We are looking at families of functions or measures on the torus which are specified by a finite number of parameters . The task, for a given family, is to look at a small numbe…
Functions tiling with several lattices
Mihail N. Kolountzakis, Effie Papageorgiou
We study the problem of finding a function with ``small support'' that simultaneously tiles with finitely many lattices in -dimensional Euclidean spaces.…
