The geometrical theory of nonlinear differential equations
originates from classical works by S. Lie and A. Bäcklund. It
obtained a new impulse in the sixties when the complete integrability
of the Korteweg–de Vries equation was found and it became clear
that some basic and quite general geometrical and algebraic structures
govern this property of integrability.
Nowadays the geometrical and algebraic approach to partial
differential equations constitutes a special branch of modern
mathematics.
In 1993, a workshop on algebra and geometry of differential equations
took place at the University of Twente (The Netherlands), where the
state-of-the-art of the main problems was fixed. This book contains a
collection of invited lectures presented at this workshop. The
material presented is of interest to those who work in pure and
applied mathematics and especially in mathematical physics.
