Abstract We establish global-in-time well-posedness of the one-dimensional hydrodynamic Gross–Pitaevskii equations in the absence of vacuum in $$(1 + H^s) times H^{s-1}$$ (1+Hs)×Hs-1 with $$s ge 1$$ s≥1 . We achieve this by a reduction via the Madelung transform to the previous global-in-time well-posedness result for the Gross–Pitaevskii equation in Koch and Liao (Adv Math 377, 2021; Adv Math 420, 2023). Our core result is a local bilipschitz equivalence of the relevant function spaces, which enables the transfer of results between the two equations.
摘要建立了无真空条件下$$(1 + H^s) times H^{s-1}$$ (1 + H s) × H s - 1 ($$s ge 1$$ s≥1)下一维水动力Gross-Pitaevskii方程的全局时适性。我们通过Madelung变换将之前的Gross-Pitaevskii方程的全局时间适定性结果简化到Koch和Liao (Adv Math 377, 2021;Adv数学420,2023)。我们的核心结果是相关函数空间的局部bilipschitz等价，它使结果在两个方程之间传递。

Abstract In this paper, we consider, from both analytical and numerical viewpoints, a thermoelastic problem. The so-called MGT model, with two different relaxation parameters, is used for both the displacements and the thermal displacement, leading to a linear coupled system made by two third-order in time partial differential equations. Then, using the theory of linear semi-groups the existence and uniqueness to this problem is proved. If we restrict ourselves to the one-dimensional case, the exponential decay of the energy is obtained assuming some conditions on the constitutive parameters. Then, using the classical finite element method and the implicit Euler scheme, we introduce a fully discrete approximation of a variational formulation of the thermomechanical problem. A main a priori error estimates result is shown, from which we conclude the linear convergence under suitable additional regularity conditions. Finally, we present some one-dimensional numerical simulations to demonstrate the convergence of the fully discrete approximation, the behavior of the discrete energy decay and the dependence on a coupling parameter.
