Calculus of variations with fractional derivatives and fractional integrals

Ricardo Almeida, Delfim F. M. Torres

We prove Euler-Lagrange fractional equations and sufficient optimality conditions for problems of the calculus of variations with functionals containing both fractional derivatives…

Isoperimetric problems on time scales with nabla derivatives

Ricardo Almeida, Delfim F. M. Torres

We prove a necessary optimality condition for isoperimetric problems under nabla-differentiable curves. As a consequence, the recent results of [M.R. Caputo, A unified view of oste…

The isoperimetric problem for Holderian curves

Ricardo Almeida, Delfim F. M. Torres

We prove a necessary stationary condition for non-differentiable isoperimetric variational problems with scale derivatives, defined on the class of Hölder continuous functions.
