Hight-order Noether's Theorem for Nonsmooth Extremals of Isoperimetric Variational Problems with Time Delay
G. S. F. Frederico, M. J. Lazo
We obtain a nonsmooth higher-order extension of Noether's symmetry theorem for variational isoperimetric problems with delayed arguments. The result is proved to be valid in the cl…
Fractional Noether's Theorem with Classical and Caputo Derivatives: constants of motion for non-conservative systems
Gastão S. F. Frederico, Matheus J. Lazo
Since the seminal work of Emmy Noether it is well know that all conservations laws in physics, \textrm{e.g.}, conservation of energy or conservation of momentum, are directly relat…
Constants of motion for Isoperimetric Variational Problems with Time Delay
G. S. F. Frederico, M. J. Lazo, M. N. F. Barreto +1
In the present work, we obtain the constants of motion for isoperimetric variational problems with time delay. We consider a constrained optimization problem where the Lagrangian f…
