Student Body:
Students planning further studies in analysis, probability, or statistics.
Math 629 is an exploration of Lebesgue measure and integration and general measure theory. This course is suitable for advanced undergraduates in mathematics and graduate students in departments outside mathematics, and is fundamental to much of graduate analysis and statistics. Math 521 (first-semester real analysis) or its equivalent will be assumed.
Background and Goals:
This is an introduction to measure and integration theory. It is particularly suitable for further studies in analysis, probability and statistics.
Alternatives:
n/a
Subsequent Courses:
Graduate courses in the subject
