Noether's theorem for higher-order variational problems of Herglotz type
Simao P. S. Santos, Natalia Martins, Delfim F. M. Torres
We approach higher-order variational problems of Herglotz type from an optimal control point of view. Using optimal control theory, we derive a generalized Euler-Lagrange equation,…
Variational problems for Holderian functions with free terminal point
Ricardo Almeida, Natália Martins
We develop the new variational calculus introduced in 2011 by J. Cresson and I. Greff, where the classical derivative is substituted by a new complex operator called the scale deri…
Variational problems of Herglotz type with time delay: DuBois-Reymond condition and Noether's first theorem
Simao P. S. Santos, Natalia Martins, Delfim F. M. Torres
We extend the DuBois-Reymond necessary optimality condition and Noether's first theorem to variational problems of Herglotz type with time delay. Our results provide, as corollarie…
