A theory of non-absolutely convergent integrals in R with singularities on a regular boundary

Specializing a recently developed axiomatic theory of non-absolutely convergent integrals in R, we are led to an integration process over quite general sets A ⊆ R with a regular boundary. The integral enjoys all the usual properties and yields the divergence theorem for vector-valued functions with singularities in a most general form. Introduction. Consider an n-dimensional vector field ~v whi...

Differential Inclusions, Non-absolutely Convergent Integrals and the First Theorem of Complex Analysis

In the theory of complex valued functions of a complex variable arguably the first striking theorem is that pointwise differentiability implies C∞ regularity. As mentioned in Ahlfors [Ah 78] there have been a number of studies [Po 61], [Pl 59] proving this theorem without use of complex integration but at the cost of considerably more complexity. In this note we will use the theory of non-absol...

satisfying zZ\ \^A < °°, if and only if f is) is bounded away from zero in the half-plane 0-3:0. This discovery amounts to a determination of the spectrum of the Banach-algebra element associated with fis), and it thus makes available for the theory of ordinary Dirichlet series the well-known theorem of Gelfand on analytic functions of Banach-algebra elements (see §24D of [7]) and its generaliz...
