Anton R. Schep

As of January 1, 2021, I am retired as a Distinguished Professor Emeritus. I will continue refereeing papers for the foreseeable future, but only papers I can do a report on quickly or which interest me highly. On this page you can find links to information on classes I have taught and
selected re- and preprints. To find information about our
department, go to the
Departmental homepage. For my
professional background, see my curriculum
vitae .

I am generally interested in the areas of Functional Analysis and Operator Theory. In particular my published research includes papers on:

- the study of linear integral operators on Banach function spaces.
- positive operators and C
_{0}-semigroups of positive operators on Banach lattices. - spectral properties, and compactness properties of special classes of operators, such as disjointness preserving operators.

*The measure of non-compactness of a disjointness preserving operator*

A slightly revised version appeared in: J. Operator Theory,**21**(1989), 397-402.*And Still One More Proof of the Radon-Nikodym Theorem*

Appeared in the Mathematical Monthly (2003). Here is*an updated and improved version.*UPDATE: When preparing a lecture for my graduate class, I decided that the second version was not as intuitive in its approach as the original version. Therefore I wrote*a third version.*much closer inspirit to the published version, but using ideas from the second version. Therefore check out this version too, if you plan to present the proof in a class.-
*Norms of positive operators on Lp-spaces*

(with Ralph E. Howard), A revision appeared in: Proceedings of the American Mathematical Society,**109**(1990), 135-146. -
*Lozanovskii's proof of Dunford's theorem*

A rather loose translation of G. Ya. Lozanovskii's paper:*N. Dunford's theorem,*Izv. Vyss Ucebn. Zaved. Matem.,**8**(1974), 58-59 (in Russian). -
*Products of Cesaro convergent sequences with applications to convex solid sets and integral operators*Proc. of the AMS 137 (2009), 579–584. -
*Products and Factors of Banach Function spaces*Appeared in Positivity. *Minkowski’s integral inequality for function norms*In this paper we give a necessary and sufficient condition on a pair of Fatou norms $\rho$ and $\lambda$ so that an inequality of the form $\rho(\lambda(f_x))\le C\lambda(\rho(f^y))$ holds for all nonnegative measurable functions $f(x, y)$. This paper appeared in Operator Theory in Function Spaces and Banach lattices, Operator Theory, Advances and Applications, vol. 75, Birkhauser, Basel–Boston–Berlin, 1995, pp. 299–308. Here we posted an updated version, which corrects an error in the published version.
