On the Riesz representation theorem and integral operators
(NISC (Pty) Ltd, http://www.nisc.co.za/, 2015-12-14)We present a Riesz representation theorem in the setting of extended integration theory as introduced in [6]. The result is used to obtain boundedness theorems for integral operators in the more general setting of spaces ... -
Fundamental Theorem of Calculus in Topological Vector Spaces
(Journal of Mathematics Extension, 2017-10)We extend the notions of integration and differentiation to cover the class of functions taking values in topological vector spaces. We give versions of the Lebesgue-Nikodym Theorem and the Fundamental Theorem of Calculus ... -
On cartesian nets and fubini-tonelli type theorem
(International Journal of Applied Physics and Mathematics, http://www.ijapm.org/, 2017-04)The notion of Cartesian net is introduced in order to provide an appropriate setting for the notion of double limit for directed functions defined on Cartesian products of spaces. As an application, we obtain extensions ... -
