Symmetries and conservation laws of the Euler equations in Lagrangian coordinates
Ravi Shankar
We consider the Euler equations of incompressible inviscid fluid dynamics. We discuss a variational formulation of the governing equations in Lagrangian coordinates. We compute var…

Sub-symmetries I. Main properties and applications
V. Rosenhaus, Ravi Shankar
We introduce a sub-symmetry of a differential system as an infinitesimal transformation of a subset of the system that leaves the subset invariant on the solution set of the entire…

On a nonlocal extension of differentiation
Ravi Shankar
We study an integral equation that extends the problem of anti-differentiation. We formulate this equation by replacing the classical derivative with a known nonlocal operator simi…
