關於這本電子書

After some measure-theoretic preliminaries, the notion of web is defined and used to construct a dimension- and metric-free setting for the differentiation of non-negative valued set functions. Conditions which guarantee the frequent existence of the derivative of one such function with respect to another are examined in detail, and then strengthened to permit integration of the derivative in case the denominator function is a measure. A Lebesgue decomposition of a function into a part which is the integral of its derivative and a remainder with derivative almost everywhere zero is obtained. The resulting theory is applied to differentiation of indefinite integrals, complex valued functions of bounded variation on the reals, and others.
