Onsager conjecture
Web1 de fev. de 2024 · This conjecture, formulated in 1949 by Lars Onsager [1], states that is a critical smoothness in the sense that solutions to the Euler equations of smoothness greater than must conserve energy and that solutions with smoothness less than might not. The positive direction of this conjecture was resolved in [2] by Constantin, E, and Titi and has ...

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, … WebThis result, together with the proof of energy conservation for α > 1 / 3 due to [Eyink] and [Constantin, E, Titi], solves Onsager’s conjecture that the exponent α = 1 / 3 marks the threshold for conservation of energy for weak solutions in the class L t ∞ C x α. The …
