On degenerations between preprojective modules over wild quivers

We study minimal degenerations between preprojective modules over wild quivers. Asymptotic properties of such degenerations are studied, with respect to codimension and numbers of indecomposable direct summands. We provide families of minimal disjoint degenerations of arbitrary codimension for almost all wild quivers and show that no such examples exist in the remaining cases.Comment: Proofs improved, several typos corrected.

Strawberry breeding for disease resistance in Dresden

Verticillium resistance is one of the most important breeding goals in strawberry resistance breeding at Dresden-Pillnitz. Resistance evaluation of cultivars, advanced selections and seedlings is realized under natural conditions at a provocation field and by artificial inoculation in the greenhouse. Introgression of Fragaria chiloensis L. (Miller) into Fragaria ×ananassa Duch. resulted in highly tolerant breeding selections. After back-crossing with cultivars of F. ×ananassa first genotypes were selected which can be evaluated in experimental cultivar trials at different locations in Germany

Reflections on my Life: In the Kingdom and the Academy

Reflections on my Life is the memoir of Thomas Olbricht, dedicated Churches of Christ minister, renowned scholar, and prolific author. Olbricht recalls his more than 50-year ministry in the Churches of Christ together with his academic career in Christian education, which includes administrative posts at the University of Iowa, Harding University, the University of Dubuque, Pennsylvania State University, Abilene Christian University, and Pepperdine University.https://digitalcommons.pepperdine.edu/heritage_center/1005/thumbnail.jp
