摘要

我们考虑了Fermi-Pasta-Ulam-Tsingou晶格的远程变体，特别是允许粒子在任意长的距离上相互作用。我们发展了允许构造孤立波解的充分条件。

Coherent Structures in Long-Range FPUT Lattices, Part I: Solitary Waves

We consider long-range variants of Fermi–Pasta–Ulam–Tsingou lattice and, in particular, allow for particles to interact over arbitrarily long distances. We develop sufficient conditions that allow for the construction of solitary wave solutions.

期刊介绍： Studies in Applied Mathematics explores the interplay between mathematics and the applied disciplines. It publishes papers that advance the understanding of physical processes, or develop new mathematical techniques applicable to physical and real-world problems. Its main themes include (but are not limited to) nonlinear phenomena, mathematical modeling, integrable systems, asymptotic analysis, inverse problems, numerical analysis, dynamical systems, scientific computing and applications to areas such as fluid mechanics, mathematical biology, and optics.
