Infinitesimal operators of rotation group and Lorentz group for differential equations and their applications. (English)
Authors: Popa Mihail, Port S. A.
Abstract
The infinitesimal operators of a linear representation of a group of rotations and the Lorentz group in the space of polynomial coefficients of the differential equations are constructed and with their help the functional bases of invariants of these groups for a quadratic differential system are found.Institutul de Matematică şi Informatica
