TY - THES A1 - Kübler, Joel T1 - Symmetry breaking in semilinear boundary value problems N2 - This thesis is concerned with the study of symmetry breaking phenomena for several different semilinear partial differential equations. Roughly speaking, this encompasses equations whose symmetries are not necessarily inherited by their solutions, which is particularly interesting for ground state solutions.
