Variational principles with fractional derivatives
Teodor M. Atanacković, Sanja Konjik, Stevan Pilipović · 2019
We consider several generalizations of the Hamilton principle and study optimality conditions involving Euler-Lagrange equations. We present the concept of the fractional complementary variational principle. Moreover, we propose an expansion formula for the fractional derivative as a tool for solving the Euler-Lagrange equations.
