  • A LOCALIZATION PRINCIPLE for ORBIFOLD THEORIES 3 Coprime Positive Integers)
    Contemporary Mathematics A Localization Principle for Orbifold Theories Tommaso de Fernex, Ernesto Lupercio, Thomas Nevins, Bernardo Uribe Dedicated to Prof. Samuel Gitler on the occasion of his 70th birthday. Abstract. In this article, written primarily for physicists and geometers, we survey several manifestations of a general localization principle for orbifold theories such as K-theory, index theory, motivic integration and elliptic genera. 1. Orbifolds In this paper we will attempt to explain a general localization principle that appears frequently under several guises in the study of orbifolds. We will begin by reminding the reader what we mean by an orbifold. The most familiar situation in physics is that of an orbifold of the type X = [M/G], where M is a smooth manifold and G is a finite group acting1 smoothly on M; namely, we give ourselves a homomorphism G → Diff(M). We make a point of distinguishing the orbifold X = [M/G] from its quotient space (also called orbit space) X = M/G. As a set, as we know, a point in X is an orbit of the action: that is, a typical element of M/G is Orb(x)= {xg | g ∈ G}. For us an orbifold X = [M/G] is a smooth category2 (actually a topological groupoid) whose objects are the points of M, X0 = Obj(X)= M, and we insist on remembering that X0 = Obj(X) is a smooth manifold. The arrows of this category arXiv:hep-th/0411037v1 2 Nov 2004 are X1 = Mor(X) = M × G again thinking of it as a smooth manifold. A typical arrow in this category is (x,g) x −→ xg, The first author was partially supported by a University of Michigan Rackham research grant and the MIUR of the Italian government, National Research Project “Geometry on Algebraic Varieties” (Cofin 2002).

  • From the Editor
    Department of Mathematics University of Wisconsin could be used as a colloquium room and as a class- room for our lecture-classes of about 100 students. We have often thought that so much of the concrete on the plaza level surrounding Van Vleck Hall (and over the classrooms on the B-levels) is wasted, and wouldn’t it be wonderful if on this under-utilized space a new wing could be built containing such a modern lecture room. Unfortunately, it does not appear that such an addition is a high priority for campus officials at this time. But the need is great. There may be no construction on Van Vleck Hall, but there is much construction going forward on campus and in downtown Madison. University Square will be closed soon to make way for new university buildings and dormitories (that landmark Italian restaurant—I am sure you know which one I mean—has already moved out and has reopened From the Editor. closer to the capital square).
