Paul David Gustav du Bois-Reymond (2 December 1831 – 7 April 1889) was a German mathematician who was born in Berlin and died in Freiburg. He was the brother of Emil du Bois-Reymond . Germany , officially the Federal Republic of Germany , is a country in Central and Western Europe, lying between the Baltic and North Seas to the north, and the Alps, Lake Constance and the High Rhine to the south.

Du bois reymond lemma

(The lemma of DuBois-Reymond) If f∈ C0(a,b) and Z b a However, before we embark on our journey, we first introduce the Holy Grail of Calculus of Variations, a beautiful result , a mathematical jewel:The Lemma of Du Bois Reymond. Lemma 1: Part (A) If is piecewise continuous on and (2), then is a constant on except at a finite number of points. 2012-10-02 · Derivatives and integrals of non-integer order were introduced more than three centuries ago, but only recently gained more attention due to their application on nonlocal phenomena. In this context, the Caputo derivatives are the most popular approach to fractional calculus among physicists, since differential equations involving Caputo derivatives require regular boundary conditions DuBois-Reymond Lemma.

The main result of the paper is a fractional du Bois-Reymond lemma for functions of one variable with Riemann-Liouville derivatives of order α ∈ (1/2, 1).

In this context, the Caputo derivatives are the most popular approach to fractional calculus among physicists, since differential equations involving Caputo derivatives require regular boundary conditions In the paper, the generalization of the Du Bois-Reymond lemma for functions of two variables to the case of partial derivatives of any order is proved.

A. VAN WIJNGAARDEN at the meeting of February 24, 1973) his note we generalize the classical lemma of Du Bois-Reymond of the calculus of variations. The main result of the paper is a fractional du Bois-Reymond lemma for functions of one variable with Riemann-Liouville derivatives of order α ∈ (1/2, 1). 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.
