Journal ArticleDOI
Hurwitz numbers and intersections on moduli spaces of curves
TL;DR: In this article, Teke et al. presented a survey of the state-of-the-art mathematics departments in Sweden, including the Department of Mathematics, University of Stockholm, S-10691, Stockholm, Sweden (e.g.
Journal ArticleDOI
Canonical models of surfaces of general type in positive characteristic
TL;DR: In this paper, the authors present a legal opinion on the applicability of commercial or impression systématiques in the context of the agreement of publication mathématique de l'I.H.É.S.
Book ChapterDOI
On The Adic Formalism
TL;DR: In this paper, a formalism for complexes of l-adic sheaves is developed, instead of just for the sheaves themselves as was done in [SGA5:Exp.V], where the need for such a generalisation has become apparent from the theory of perverse sheaves.
Journal ArticleDOI
On Hurwitz numbers and Hodge integrals
TL;DR: In this paper, an explicit formula for the number of topologically different ramified coverings C → CP1 (C is a compact Riemann surface of genus g) with only one complicated branching point in terms of Hodge integrals over the moduli space with marked points was given.

The Grothendieck group of algebraic stacks
TL;DR: In this article, a Grothendieck group of algebraic stacks with affine stabilisers is introduced, and several invariants of elements in this group are discussed, the most important of which is an extension of the Euler characteristic (of cohomology with compact support).
