非等温条件下多相变模型的锐界面极限

Sharp interface limit of a multi-phase transitions model under nonisothermal conditions

Riccardo Cristoferi, Giovanni Gravina

摘要:

考虑了向量Modica-Mortola泛函,并研究了其收敛到锐界面模型的问题.本文的新颖之处在于势阱不是常数,而是依赖于域$Ω$中的空间位置。质量约束的最小化问题和Dirichlet边界条件的情况下也被处理。证明依赖于对势诱导的简并度规的最小测地线的精确理解。

英文摘要:

A vectorial Modica--Mortola functional is considered and the convergence to a sharp interface model is studied. The novelty of the paper is that the wells of the potential are not constant, but depend on the spatial position in the domain $Ω$. The mass constrained minimization problem and the case of Dirichlet boundary conditions are also treated. The proofs rely on the precise understanding of minimizing geodesics for the degenerate metric induced by the potential.
