The Lagrangians with linear velocities and with higher velocities are investigated and the corresponding difference Euler-Lagrange equations and Hamiltonians are found.eninfo:eu-repo/semantics/closedAccessDiscrete MathematicsVariational PrinciplesConference Object10.1063/1.22050332-s2.0-33845575431
