Ayoub's work.

arXiv:1002.1686 Notes on Beilinson's "How to glue perverse sheaves" from arXiv Front: math.CT by Ryan Reich The titular, foundational work of Beilinson not only gives a technique for gluing perverse sheaves but also implicitly contains constructions of the nearby and vanishing cycles functors of perverse sheaves. These constructions are completely elementary and show that these functors preserve perversity and respect Verdier duality on perverse sheaves. The work also defines a new, "maximal extension" functor, which is left mysterious aside from its role in the gluing theorem. In these notes, we present the complete details of all of these constructions and theorems.

math/9908107 Notes on Perverse Sheaves and Vanishing Cycles from arXiv Front: math.AG by David B. Massey 1 person liked this A working mathematician's summary of many results on the derived category, perverse sheaves, and vanishing cycles. This is the February 2010 version.

Should set up a database for varieties, to absorb examples, and things that are known. For example all the exercises in Hartshorne (at least the first chapter). Other sources: Dieudonne

Brauer-Severi varieties, see Jahnel in AG/Various

arXiv:1008.3825 Algebraic surfaces and hyperbolic geometry from arXiv Front: math.AG by Burt Totaro This is a survey of the Kawamata-Morrison cone conjecture on the structure of Calabi-Yau varieties and more generally Calabi-Yau pairs. We discuss the proof of the cone conjecture for algebraic surfaces, with plenty of examples.

We show that the automorphism group of a K3 surface need not be commensurable with an arithmetic group, which answers a question by Mazur.

arXiv:0908.4241 Lectures on curves on varieties -- Lisbon, 2009 from arXiv Front: math.AG by János Kollár These lectures give a short introduction to the study of curves on algebraic varieties. After an elementary proof of the dimension formula for the space of curves, we summarize the basic properties of uniruled and of rationally connected varieties. At the end, some connections with symplectic geometry are considered.

arXiv:1103.3156 The Expanding Zoo of Calabi-Yau Threefolds from arXiv Front: math.AG by Rhys Davies This is a short review of recent constructions of new Calabi-Yau threefolds with small Hodge numbers and/or non-trivial fundamental group, which are of particular interest for model-building in the context of heterotic string theory. The two main tools are topological transitions and taking quotients by actions of discrete groups. Both of these techniques can produce new manifolds from existing ones, and they have been used to bring many new specimens to the previously sparse corner of the Calabi-Yau zoo where both Hodge numbers are small. Two new manifolds are also obtained here from hyperconifold transitions, including the first example with fundamental group S3, the smallest non-Abelian group.
