摘要

This chapter extends the concepts of Lebesgue measure and integration to higher dimensions. The structure of open sets in \(\mathbb {R}^2\) is studied. Topics include Lebesgue outer measure, measure, measurable functions, and Lebesgue integration in \(\mathbb {R}^N\) . Additionally, Fubini’s theorem and its consequences are explored, providing a deeper understanding of measure and integration in higher-dimensional spaces.
