[PDF][PDF] Smooth Deligne-Mumford compactifications by means of Prym level structures

EJN Looijenga - Journal of Algebraic Geometry, 1994 - researchgate.net
We show that the Deligne {Mumford compactification of the moduli space of smooth complex
curves of genus g admits a smooth Galois covering whose general point classifies curves …

Arrangements, KZ systems and Lie algebra homology

EJN Looijenga - LONDON MATHEMATICAL SOCIETY LECTURE …, 1999 - books.google.com
The Knizhnik-Zamolodchikov equations were originally defined in terms of a local system
associated to tuples of finite dimensional irreducible representations of SU₂, but were soon …

Construction of canonical stratifications

CG Gibson, K Wirthmüller, AA du Plessis… - Topological stability of …, 1976 - Springer
Ideally (returning to the general situation) one seeks stratifications for which the local
topological type of'the pair (M, v) is constant on each stratum. From this point of view the …

[BOEK][B] M_g is a union of g-1 affine open subsets

EJN Looijenga - 1998 - Citeseer
We prove the assertion of the title. This implies that the cohomological dimension of Mg is≤
g− 2 for quasi-coherent sheaves (this amplifies Diaz’s theorem which says that Mg has no …

Proof of the topological stability theorem

CG Gibson, K Wirthmüller, AA du Plessis… - Topological Stability of …, 1976 - Springer
Throughout this chapter N and P are fixed manifolds and their dilnensions are denoted by
nand p respectively. § l Multi-transversality In the next sections we will encounter the following …

Unfoldings of smooth map-germs

CG Gibson, K Wirthmüller, AA du Plessis… - Topological Stability of …, 1976 - Springer
The mathematics described here arises from the study of smooth of mappings, and in particular
the associated local theory. For mappings, smooth stability is easily defined: a mapping …

The homotopy type of the Baily–Borel and allied compactifications

J Chen, E Looijenga - Homology, Homotopy and Applications, 2021 - intlpress.com
