Du bois reymond lemma

I give the proof of the theorem of wider integiability and of the uniformity of this integrability for the set of all suhintervals of the interval of integration by a process somewhat different from du Bois-Reymond's process and in a desirably explicit form. Emil Heinrich Du Bois-Reymond (Berlino, 7 novembre 1818 – Berlino, 26 dicembre 1896) è stato un fisiologo tedesco.Fondatore della moderna elettrofisiologia, è conosciuto per le sue ricerche sull'attività dell'elettricità nei nervi e nelle fibre muscolari. 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 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.

It is a generalization of well known results of such a type for the Riemann-Liouville and Caputo derivatives. Next, we use this lemma to investigate critical points of a some Lagrange functional (we derive the Euler-Lagrange equation for Du Bois-Reymond nació en Berlín, donde desarrollaría su vida laboral. Uno de sus hermanos pequeños fue el matemático Paul du Bois-Reymond (1831–1889). La familia era de origen hugonote.
