The Kurzweil-Henstock Integral for Undergraduates

This beginners' course provides students with a general and sufficiently easy to grasp theory of the Kurzweil-Henstock integral. The integral is indeed more general than Lebesgue's in R^N, but its construction is rather simple, since it makes use of Riemann sums which, being geometrically viewable, are more easy to be understood.
