Αγαπητές και αγαπητοί,
εκ μέρους της Καθηγήτριας του Εργαστηρίου Εφαρμοσμένων Μαθηματικών Μαρίας Χατζηνικολάου, σας
ενημερώνουμε για την ακόλουθη διάλεξη.
Our speaker for tomorrow (Tuesday) 16 of November, 2021 15:30 (UK time) is
Symmetry Breaking for Ground States of Biharmonic Nonlinear Schrödinger Equations
"We consider ground states solutions, suitably defined as energy minimizers, of a class of semilinear biharmonic (fourth-order) Schrödinger equations. By exploiting a connection to the adjoint Stein–Tomas inequality on the unit sphere and by using trial functions related to Knapp’s example, we prove a symmetry breaking result for ground state solutions, which is in striking contrast to the well-known results of radial symmetry for ground states of classical second-order nonlinear Schrödinger equations. We also discuss symmetry breaking for a minimization problem with constrained mass and for a related problem on the unit ball subject to Dirichlet boundary conditions.
This is joint work with Enno Lenzmann (Universität Basel)."
