The Kurzweil-Henstock Integral for Undergraduates , 1st ed. 2018 A Promenade Along the Marvelous Theory of Integration Compact Textbooks in Mathematics Series

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. The theory is developed also for functions of several variables, and for differential forms, as well, finally leading to the celebrated Stokes?Cartan formula. In the appendices, differential calculus in R^N is reviewed, with the theory of differentiable manifolds. Also, the Banach?Tarski paradox is presented here, with a complete proof, a rather peculiar argument for this type of monographs.
