Noether-type theorem for fractional variational problems depending on fractional derivatives of functions
M. J. Lazo, G. S. F. Frederico, P. M. Carvalho-Neto
In the present work, by taking advantage of a so-called practical limitation of fractional derivatives, namely, the absence of a simple chain and Leibniz's rules, we proposed a gen…
Noether theorem for action-dependent Lagrangian functions: conservation laws for non-conservative systems
M. J. Lazo, J. Paiva, G. S. F. Frederico
In the present work, we formulate a generalization of the Noether Theorem for action-dependent Lagrangian functions. The Noether's theorem is one of the most important theorems for…
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…
