Variational principles for differential equations with symmetries and conservation laws. II: Polynomial differential equations
The authors continue their study of the generalized Noether theorem, started in part I [ibid. 299, 191-222 (1994; Zbl 0804.49030)] by considering differential operators \(D\) which are polynomial functions of dependent variables and their derivatives.
