Leçons sur les fonctions de variables réelles et les développements en séries de polynomes professées à l'École normale supérieure. Rédigées par Maurice Fréchet. Avec des notes par Paul Painlevé et Henri Lebesgue

<p><i>Leçons sur les fonctions de variables réelles et les développements en séries de polynomes</i> presents a detailed exploration of real variable functions and polynomial series expansions. Based on lectures given at the prestigious École Normale Supérieure and meticulously transcribed by Maurice Fréchet this work offers insights into early 20th-century mathematical thought. Enriched with notes by eminent mathematicians Paul Painlevé and Henri Lebesgue this volume provides a valuable resource for understanding the development of mathematical analysis. This historical text captures the rigor and intellectual depth of its time making it an essential addition to any mathematics collection.</p><p>This work has been selected by scholars as being culturally important and is part of the knowledge base of civilization as we know it.
