A Liouville theorem for ancient solutions to a semilinear heat equation and its elliptic counterpart
Christos Sourdis
We establish the nonexistence of nontrivial ancient solutions to the nonlinear heat equation which are smaller in absolute value than the self-similar radial si…

Thomas-Fermi approximation for coexisting two component Bose-Einstein condensates and nonexistence of vortices for small rotation
Amandine Aftalion, Benedetta Noris, Christos Sourdis
We study minimizers of a Gross--Pitaevskii energy describing a two-component Bose-Einstein condensate confined in a radially symmetric harmonic trap and set into rotation. We consi…

Notes on Periodic Solitons
I. Bakas, C. Sourdis
We consider static solutions of the sine-Gordon theory defined on a cylinder, which can be either periodic or quasi-periodic in space. They are described by the different modes of…
