The theory of integration

Abstract

The object of small treatises of this kind is to enable the general student to gain rapid access to the various branches of Modern Mathematics, thereby preventing this science from breaking up into a number of disconnected parts, each belonging to its own specialist and closed to the outsider. Mathematics must form a whole, any progress in one of its parts stimulating advance in the others and raising new problems; when a branch is severed from the tree, it dies.
