INTEGRATION AND PROBABILITY Bengt Ringnér, Matematisk Statistik i Lund The Lebesgue integral was invented to make life easier when it comes to interchanging the orders between limits, infinite sums, and integrals. Later it became the foundation of modern probability theory. After soon a hundred years it seems time that the methods should be made available to other persons than majors in mathematics. The seminar will be a humble attempt to convey the principles in a way intelligible at least to persons with a paradigm in elementary probability.
