In the paper, we derive a fractional version of the Du Bois-Reymond lemma for a generalized Riemann-Liouville derivative (derivative in the Hilfer sense). B. DUBOIS-REYMOND'S LEMMA. In this section we improve the above mentioned result of [4] by the analogue of the Dubois-Reymond lemma: THEOREM 1. 1. N Dunford, J.T SchwartzLinear Operators. (1963).

extremals are DuBois-Reymond extremals, and the result gives a proper ex- tension of the Calculus of variations, Euler-Lagrange extremals, DuBois- Reymond Next Lemma gives a necessary and sufficient condition for Jm [x(·)], m ≥ 1, Du Bois-Reymond's contribution. There is something called a fundamental lemma of calculus of variations. Du Bois-Reymond (1831-1889) proved it.
