Quasi-Noether systems and quasi-Lagrangians
V. Rosenhaus, Ravi Shankar
We study differential systems for which it is possible to establish a correspondence between symmetries and conservation laws based on Noether identity: quasi-Noether systems. We a…

Sub-symmetries II. Sub-symmetries and Conservation Laws
V Rosenhaus, Ravi Shankar
In our previous paper, the concept of sub-symmetry of a differential system was introduced, and its properties and some applications were studied. It was shown that sub-symmetries…

Second Noether theorem for quasi-Noether systems
V. Rosenhaus, Ravi Shankar
Quasi-Noether differential systems are more general than variational systems and are quite common in mathematical physics. They include practically all differential systems of inte…
