Exploiting the finite span of compactons we use the K ( m , n ) Equation to develop an approximate description of early and late stages of their interaction.

Using a priori estimates we prove that initially nonnegative, smooth and compactly supported solutions of the equations must lose their smoothness within a finite time. Formation of a singularity is a prerequisite for the subsequent emergence of comp

Using a Lotka–Volterra type system on a hexagonal lattice we derive and study a novel, strongly nonlinear dispersive equation u t = ∂ x ( u + Δ u ) n , n > 1 , the n-Cubic equation, which supports the formation and propagation of planar compacto

In this letter we re-address a class of genuinely nonlinear third order dispersive equations; C 1 ( m , a , b ) : u t + ( u m ) x + 1 b [ u a ( u b ) x x ] x = 0 , which among other solitary structures admit compactons, and demonstrate that certain s

We present two improved quasi-continuous models of dense, strictly anharmonic chains. The direct expansion which includes the leading effect due to lattice dispersion, results in a Boussinesq-type PDE with a compacton as its basic solitary mode. With

A third order dispersive equation u t + ( u m ) x + 1 b [ u a ∇ 2 u b ] x = 0 is used to explore two very different classes of compact patterns. In the first, the prevailing singularity at the edge induces traveling compactons, solitary waves with

A Klein–Gordon model on a chain or a rectangular lattice endowed with cubic inter-site and on-site forces is presented. It supports a plethora of strictly compact stable discrete breathers which are pinned at all times to their initial support. In

As though to compensate for the rarity of multidimensional integrable systems, non-integrable spatial extensions of many of the well known dispersive equations on the line exhibit a remarkable variety of solitary patterns unavailable in 1D. In the pr

We present and study a class of Lotka–Volterra chains with symmetric -neighbors interactions. To identify the types of solitary waves which may propagate along the chain, we study their quasi-continuum approximations which, depending on the couplin
