On the hierarchy of partially invariant submodels of differential equations

Preprint English OPEN
Golovin, Sergey V.;
(2007)

It is noticed, that partially invariant solution (PIS) of differential equations in many cases can be represented as an invariant reduction of some PIS of the higher rank. This introduce a hierarchic structure in the set of all PISs of a given system of differential equ... View more
