WebJun 6, 2024 · The mathematical theory of the classical Stefan problem in one space dimension has been developed between 1947 and 1967 mainly by L. Rubinstein (see ), … WebApr 13, 2024 · By using a classical framework for convergence analysis of gradient descent algorithms, the authors show that their method’s convergence rate is consistent with that of gradient descent in the non-convex setting under the typical assumption of l-smoothness and a feasible choice of step sizes.
The Classical Stefan Problem by S. C. Gupta (ebook)
WebA survey of the results obtained in (22) is presented. In (22) the authors prove the existence of a local-in-time solution for the classical two-phase Stefan problem that is analytic in space and time. The result is based on Lp maximal regularity, which is proved first, and the implicit function theorem. WebAs far as we know, global existence theorems of classical solutions for the tWo-phase Stefan problem were considered only by Rubinstein [4], However, there is a fundamental gap in his proof of existence. In §8 we explain the nature of this gap. Thus it is not known, at this point, whether classical solutions do in fact exist globally. mha pro hero characters names

WebBoth one-dimensional two-phase Stefan problems with the thermodynamic equilibrium condition θ ( R ( t), t) = 0, and with the kinetic rule θ ( R ( t), t) = − ε R ˙ ( t) at the moving boundary x = R ( t) are considered. We study the properties of the regular solutions of the problem with equilibrium condition.
