Onsager conjecture

Web24 de fev. de 2016 · In (Isett, Regularity in time along the coarse scale flow for the Euler equations, 2013), the first author proposed a strengthening of Onsager’s conjecture on the failure of energy conservation for incompressible Euler flows with Hölder regularity not exceeding $${1/3}$$ 1 / 3 . This stronger form of the conjecture implies that anomalous …

Non-uniqueness for the Euler Equations up to Onsager’s Critical ...

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. In-deed, Onsager explicitly states in [26] (cp. also [18]) that this should be the case. For the scheme (1.6) in this paper the interpretation is that Web1 de mai. de 2024 · In the present paper, we conjecture the precise relationship and give some supporting evidence. This evidence consists of some computer checks on SageMath due to Travis Scrimshaw, a proof of the analog conjecture for the Onsager algebra O, and a proof of our conjecture for a homomorphic image of O q called the universal Askey … eagle springs new homes https://longbeckmotorcompany.com

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, … WebWe prove that given any β<1/3, a time interval [0,T], and given any smooth energy profile e:[0,T]→(0,∞), there exists a weak solution v of the three-dimensional Euler equations such that v∈Cβ([0,T]×T3), with e(t)=∫T3 v(x,t) 2dx for all t∈[0,T]. Moreover, we show that a suitable h-principle holds in the regularity class Cβt,x, for any β<1/3. The implication of this is that … Web4 de abr. de 2024 · In this paper we deal with the Cauchy problem for the incompressible Euler equations in the three-dimensional periodic setting.
