Onsager conjecture

WebIn this article, two classes of sufficient conditions of weak solutions are given to guarantee the energy conservation of the compressible Euler equations. Our strategy is to introduce a test function φ(t)vϵ to derive the total energy. The velocity field v needs to be regularized both in time and space. In contrast to the noncompressible Euler equations, … Web23 de jul. de 2024 · Onsager's Conjecture for Admissible Weak Solutions. Tristan Buckmaster, Tristan Buckmaster.

Web2 de jul. de 2024 · The Onsager’s conjecture has two parts: conservation of energy, if the exponent is larger than 1 / 3, and the possibility of dissipative Euler solutions, if the exponent is less than or equal to 1 / 3. The paper proves half of the conjecture, the conservation part, in bounded domains. WebConvex integration techniques have been used to produce solutions with precise regularity, which are necessary for the resolution of the Onsager conjecture for the 3D Euler equations, or solutions with intermittency, which are necessary for the construction of dissipative weak solutions for the Navier-Stokes equations.

Webpart (b) of Onsager’s conjecture is that in a dissipative solution the active modes, among which the energy transfer takes place, should be (at most) exponentially distributed.
