Du bois reymond lemma

Lecture Notes in Mathematics, vol 1114. 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 over 2; 1). Proof of this lemma is based on a theorem on the integral representation of a function possessing the fractional derivative of order α ∈ (1 over 2; 1) and on a fractional variant of the theorem on the integration by parts.

Then we can use Du Bois-Reymond's lemma, which states Let $H$ be the set $\{h\in C^1([a,b]):h(a)=h(b)=0\}$ . If $f\in C([a,b])$ and $\int_a^b f(x)h'(x)\,\text{d}x=0$ for all $h\in H$ , then $f(x)$ is constant for all $x\in[a,b]$ .

Working at the University of Berlin (1836–96) under Johannes Müller, whom he later succeeded as professor of physiology (1858), Du Bois-Reymond 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 .

Emil du Bois-Reymond is the greatest unknown intellectual of the nineteenth century. Emil Heinrich du Bois-Reymond desenvolveu, construiu e refinou vários instrumentos científicos, como o galvanômetro, para gerar altas tensões variáveis. Seu principal mérito reside em seu trabalho meticuloso ao longo dos anos, que se caracterizou pela precisão constante nas medições e uma grande criatividade e habilidade na construção dos instrumentos de medição.

In the paper, the generalization of the Du Bois-Reymond lemma for functions of Du Bois-Reymond also established that a trigonometric series that converges to a continuous function at every point is the Fourier series of this function. He is also associated with the fundamental lemma of calculus of variations of which he proved a refined version based on that of Lagrange .
