Projective contact log varieties
Adrian Langer
We study contact structures on smooth complex projective varieties with a simple normal crossing divisor, generalizing some well-known results concerning the non-logarithmic case.…

Bridgeland stability conditions on normal surfaces
Adrian Langer
We prove a new version of Bogomolov's inequality on normal proper surfaces. This allows to construct Bridgeland's stability condition on such surfaces. In particular, this gives th…

Moduli Spaces for Principal Bundles in Arbitrary Characteristic
T. L. G'omez, A. Langer, A. H. W. Schmitt +1
In this article, we solve the problem of constructing moduli spaces of semistable principal bundles (and singular versions of them) over smooth projective varieties over algebraica…
