| 11:00 - 12:00 Lecture Tilting Theory over Commutative Rings School MATHEMATICS Tilting theory has a long history originating in the representation theory of finite-dimensional algebra [Hap] and algebraic geometry [Bei]. Later, infinitely generated tilting modules were introduced as a formal generalization of tilting objects representing derived equivalences. It turned out recently that in the context of commutative rings, there is a very geometric classification of tilting modules up to additive equivalence in terms of support and using very well-known homological theories [APST], [HS]. If time allows, I will touch recent results which elaborate the relevance of the geometric point of view further - the Zarisk ... 13:00 - 14:00 Lecture Tilting Theory over Commutative Rings School MATHEMATICS Tilting theory has a long history originating in the representation theory of finite-dimensional algebra [Hap] and algebraic geometry [Bei].

This is the first global set of diffractive PDFs deter-mined within the xFitter framework. This analysis is motivated by all available and most up-to-date data on inclusive diffractive deep inelastic scattering (diffractive DIS). We study the impact of the H1/ZEUS combined data by producing a variety of determinations based on reduced data sets. We find that these data sets have a significant impact on the diffractive PDFs with some substantial reductions in uncertainties. ... 16:00 - 18:00 Neuroimaging Journal Club Alpha Oscillations Related to Anticipatory Attention Follow Temporal Expectations School COGNITIVE SCIENCES Venue: School of Cognitive Sciences, Institute for Research in Fundamental Sciences (IPM), Opposite the ARAJ, Artesh Highway, Tehran, Iran ... 9:30 - 10:30 Lecture G-groups School MATHEMATICS Let G be a group. A G-group is a pair (H,f), where H is a group and f:G --> Aut(H) is a group homomorphism. The category G-Grp of all G-groups shows a behaviour that is a very pleasant combination of the behaviour of groups and that of left modules over a ring. We will describe several properties of this category G-Grp. In particular, the existence, discovered by Remak, of the central automorphism in the statement of the classical Krull-Schmidt Theorem for finite groups has a natural explanation interpreting this result in the category G-Grp. ... |
