具有在位双稳态非简并势格点的波前传播:多重性、分岔和通向混沌的途径

Front propagation in lattices with on-site bistable non-degenerate potential: multiplicity, bifurcations and route to chaos

I. B. Shiroky, O. V. Gendelman

摘要:

具有非简并在位势的耦合振子模型中跃迁前沿的传播通常用行波来考虑。我们表明,系统动力学可以重新表述为一个隐式的地图结构,行波对应稳定的不动点。因此,这种波的稳定性损失应遵循众所周知的一般分叉情况。然后,人们可以期待大量的定性不同的传播前沿解决方案-多稳定,多周期,准周期和混沌。

英文摘要:

Propagation of transition fronts in models of coupled oscillators with non-degenerate on-site potential is usually considered in terms of travelling waves. We show that the system dynamics can be reformulated as an implicit map structure, and the travelling waves correspond to stable fixed points. Therefore, the loss of stability of such waves should follow well-known generic bifurcation scenarios. Then, one can expect a plethora of qualitatively different propagating-front solutions - multistable, multi-periodic, quasiperiodic and chaotic.
