Point classification of 2nd order ODEs: Tresse classification revisited and beyond
Author
Kruglikov, BorisAbstract
In 1896 Tresse gave a complete description of relative differential invariants
for the pseudogroup action of point transformations on the 2nd
order ODEs. The purpose of this paper is to review, in light of modern
geometric approach to PDEs, this classification and also discuss the role
of absolute invariants and the equivalence problem.
