### Trigonometrisk Fourier-serie. Tillämpning av enstaka

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. Some application of this theorem to the coercive Dirichlet problem is given. law of excitation: a motor nerve responds, not to the absolute value, but to the alteration of value from moment to moment, of the electric current; that is, rate of change of intensity of the current is a factor in determining its effectiveness.
