WebThese notes are based on a series of lectures given at the meeting Journées EDP in Roscoff in June 2015 on recent developments concerning weak solutions of the Euler equations and in particular recent progress concerning the construction of Hölder continuous weak solutions and Onsager’s conjecture. Web16 de mai. de 2012 · For any θ<1/10 we construct periodic weak solutions of the incompressible Euler equations which dissipate the total kinetic energy and are Hölder-continuous with exponent θ. A famous conjecture of Onsager states the existence of such dissipative solutions with any Hölder exponent θ<1/3. Our theorem is the first result in …
Weband [Kui55]) they proposed to approach the remaining statement of the Onsager’s conjecture in a. similar way (cf. [DLS12]). Indeed in [DLS13] and [DLS14] they were able to giv e the first examples.

Web3 de dez. de 2024 · In 1949, L. Onsager formulated the following conjecture: all solutions of the incompressible Euler equations which are H"older continuous with exponent bigger than $1/3$ conserve the total kinetic energy, while there are solutions which dissipate the total kinetic energy in the space of H"older continuous functions with exponent smaller … WebThis conjecture has been intensively studied by many mathematicians for the last two decades.
