Toland, J. F. Non-existence of global energy minimisers in Stokes waves problems. (English) Zbl 1292.76024 Discrete Contin. Dyn. Syst. 34, No. 8, 3211-3217 (2014). Summary: Recently it was shown that a wave profile which minimises total energy, elastic plus hydrodynamic, subject to the vorticity distribution being prescribed, gives rise to a steady hydroelastic wave. Using this formulation, the existence of non-trivial minimisers leading to such waves was established for certain non-zero values of the elastic constants used to model the surface. Here we show that when these constants are zero, global minimisers do not exist except in a unique set of circumstances.
