Bäcklund Transformations and Integrable Discrete
Equations.
(See also: resources
and, in particular, research topics.)
Groups of discrete transformations between the solution spaces of an
equation or related equations have numerous applications and originate, in
essence, in the works of
Darboux
and other geometers of the last part of the nineteenth century. They have
been particularly fruitful in soliton theory where they are a machine for
generating multi-soliton solutions. However, they also generate lattices
of equations which themselves have integrable structure.
