Bijective correspondences are established between (1) silting objects, (2) simple-minded collections, (3) bounded t-structures with length heart and (4) bounded co-t-structures. These correspondencesâ€¦ (More)

Rhodopsin-containing disks, isolated from rod outer segments of bovine retina, align at high magnetic fields with their membrane normal parallel to the magnetic field. After light-activation ofâ€¦ (More)

A general framework for cluster tilting is set up by showing that any quotient of a triangulated category modulo a tilting subcategory (that is, a maximal oneorthogonal subcategory) carries anâ€¦ (More)

Incoherent quasi-elastic neutron scattering is applied to study the local diffusion and chain dynamics of L-alpha-diplamiotylphosphatidylcholine molecules in oriented model membranes. Differentâ€¦ (More)

Endomorphism rings of a special class of tilting complexes for selfinjective algebras and for Gorenstein orders are computed. As applications we get short proofs of generalizations of results ofâ€¦ (More)

Let A be a finite dimensional simple Lie algebra over the complex numbers. It is shown that a module is complete (or relatively complete) in the sense of Enright if and only if it is injectivelyâ€¦ (More)

Let G be a finite dimensional semisimple Lie algebra over the complex numbers. Let A be the finite dimensional algebra of a (regular or singular) block of the BGGâ€“ category O. By results of Soergelâ€¦ (More)

We construct a generalization of the BGGâ€“category O, whose blocks correspond to standardly stratified algebras. We prove reciprocity formulae in these categories and present two classes of examples.

Let A be a quasiâ€“hereditary algebra with triangular decomposition CACop ' C âŠ—S Cop such that all Verma modules are semisimple over Cop. Then we show: gldim(A) = 2 Â· gldim(C). Applying this formula toâ€¦ (More)
