Elementary Introduction to the Lebesgue Integral - Steven G Krantz

. .

Résumé :
This textbook offers a rare opportunity to teach Lebesgue integration to undergraduates. Focusing on the real line, the author introduces the topic in an accessible way, thus encouraging students to dig into this mainstay of mathematical analysis earlier than the traditional graduate level course.
