2 $\begingroup$ I know thats OF THE DU BOIS-REYMOND LEMMA FOR FUNCTIONS OF TWO VARIABLES TO THE CASE OF PARTIAL DERIVATIVES OF ANY ORDER DARIUSZ IDCZAK Institute of Mathematics, L´ od´z University Stefana Banacha 22, 90-238 L´ od´z, Poland Abstract. 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 .
