On integration of vector functions with respect to vector measures

José Rodríguez (2006)

Czechoslovak Mathematical Journal

We study integration of Banach space-valued functions with respect to Banach space-valued measures. We focus our attention on natural extensions to this setting of the Birkhoff and McShane integrals. The corresponding generalization of the Birkhoff integral was first considered by Dobrakov under the name S * -integral. Our main result states that S * -integrability implies McShane integrability in contexts in which the later notion is definable. We also show that a function is measurable and McShane integrable...

On Kurzweil-Stieltjes integral in a Banach space

Giselle A. Monteiro, Milan Tvrdý (2012)

Mathematica Bohemica

In the paper we deal with the Kurzweil-Stieltjes integration of functions having values in a Banach space X . We extend results obtained by Štefan Schwabik and complete the theory so that it will be well applicable to prove results on the continuous dependence of solutions to generalized linear differential equations in a Banach space. By Schwabik, the integral a b d [ F ] g exists if F : [ a , b ] L ( X ) has a bounded semi-variation on [ a , b ] and g : [ a , b ] X is regulated on [ a , b ] . We prove that this integral has sense also if F is regulated on [ a , b ] ...

On locally solid topological lattice groups

Abdul Rahim Khan, Keith Rowlands (2007)

Czechoslovak Mathematical Journal

Let ( G , τ ) be a commutative Hausdorff locally solid lattice group. In this paper we prove the following: (1) If ( G , τ ) has the A (iii)-property, then its completion ( G ^ , τ ^ ) is an order-complete locally solid lattice group. (2) If G is order-complete and τ has the Fatou property, then the order intervals of G are τ -complete. (3) If ( G , τ ) has the Fatou property, then G is order-dense in G ^ and ( G ^ , τ ^ ) has the Fatou property. (4) The order-bound topology on any commutative lattice group is the finest locally solid topology on...
