NODES

NODES is a computer algebra program dedicated to the analysis of systems of nonlinear ODEs. It is based on the quasimonomial transformation theory. In that theory, a system of ODEs is represented by a couple of matrices and only these are manipulated. Since only algebraic manipulations have to be done, the theory is easy to implement in a computer algebra language and we obtain an efficient program. In its present form, NODES is mainly dedicated to finding integrability conditions for systems of ODEs and constructing the corresponding first integrals.
