Integrable systems | Solitons | Exactly solvable models
The Toda lattice, introduced by Morikazu Toda, is a simple model for a one-dimensional crystal in solid state physics. It is famous because it is one of the earliest examples of a non-linear completely integrable system. It is given by a chain of particles with nearest neighbor interaction, described by the Hamiltonian and the equations of motion where is the displacement of the -th particle from its equilibrium position, and is its momentum (mass ), and the Toda potential . (Wikipedia).
Lattice multiplication is a multiplication method that allows you multiply any two numbers quickly using a table. It is especially useful in multiplying large numbers, with less mess and confusion than standard long multiplication. This method has many names - Lattice multiplication, gel
