Non-existence of Global Energy-Minimisers in Stokes Wave Problems
نویسنده
چکیده
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. Here we show that when these constants are zero, global minimisers do not exist except in a unique set of circumstances.

Copolymer-homopolymer blends: global energy minimisation and global energy bounds
We study a variational model for a diblock-copolymer/homopolymer blend. The energy functional is a sharp-interface limit of a generalisation of the Ohta-Kawasaki energy. In one dimension, on the real line and on the torus, we prove existence of minimisers of this functional and we describe in complete detail the structure and energy of stationary points. Furthermore we characterise the conditio...
متن کاملGlobal existence for a damped wave equation and convergence towards a solution of the Navier-Stokes problem
In two and three space dimensions, and under suitable assumptions on the initial data, we show global existence for a damped wave equation which approaches, in some sense, the Navier-Stokes problem. The proofs are based on a refinement of the energy method in [2]. In this paper, we improve the results of [2] and [8]. We relax the regularity of the initial data of the former, even though we stil...

We provide a necessary and sufficient condition for strict local minimisers of differences of convex (DC) functions, as well as related results pertaining to characterisation of (non-strict) local minimisers, and uniqueness of global minimisers.

متن کاملExistence of Global Solutions to Free Boundary Value Problems for Bipolar Navier-stokes-possion Systems
In this article, we consider the free boundary value problem for one-dimensional compressible bipolar Navier-Stokes-Possion (BNSP) equations with density-dependent viscosities. For general initial data with finite energy and the density connecting with vacuum continuously, we prove the global existence of the weak solution. This extends the previous results for compressible NS [27] to NSP.
