Onsager theorem
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, … WebUltimately Theorem 2.2 states that a (suitable form of) Gauss’ Theorema Egregium holds for C1; immersions as soon as > 2 3. In [20] we discov-ered a very short proof of Borisov’s …
