| 10:00 - 11:00 Seminar Modeling of Migration and Chemotaxis in Dictyostelium discoideum School BIOLOGICAL SCIENCES Abstract: Chemotaxis is a ubiquitous biological phenomenon in which cells detect a spatial gradient of chemoattractant, and then move towards the source. This kind of movement plays a central role in the life of both prokaryotes and eukaryotes. It is crucial for various processes like wound healing, cancer metastasis or embryogenesis. One of the most widely studied model organisms for eukaryotic chemotaxis is the amoeba Dictyostelium discoideum, which shares many of its biochemical pathways with mammalian cells. These amoebae extend pseudopodium - a temporary actin-based protrusion of their body membrane to probe the medium and crawl ... 11:00 - 13:00 Lecture DG Homological Algebra and Vanishing of (Co)homology over Local Rings School MATHEMATICS The use of techniques from differential graded (DG) homological algebra was established by Avramov, Buchsbaum, Eisenbud, Halperin, Kustin, Miller, and Weyman in commutative algebra, for instance, via DG algebra structures on Koszul complexes and free resolutions. It has been shown recently that these techniques can be applied to solve non-trivial problems in commutative algebra. In this talk, we will discuss the following major problems: Auslander-Reiten Conjecture (1975). If M is a finitely generated module over a local ring R with Ext^i_R(M, M ? R) = 0 for all i large enough, ... |
