Robert MacPherson and arithmetic groups [PDF]
, 2006 We survey contributions of Robert MacPherson to the theory of arithmetic groups. There are two main areas we discuss: (i) explicit reduction theory for Siegel modular threefolds, and (ii) constructions of compactifications of locally symmetric spaces ...

A Strong Coupling Test of S-Duality [PDF]
, 1994 By studying the partition function of $N=4$ topologically twisted supersymmetric Yang-Mills on four-manifolds, we make an exact strong coupling test of the Montonen-Olive strong-weak duality conjecture.

Cop and robber game and hyperbolicity
, 2014 In this note, we prove that all cop-win graphs G in the game in which the robber and the cop move at different speeds s and s' with s'0, this establishes a new - game-theoretical - characterization of Gromov hyperbolicity.

Transplantation of Local Nets and Geometric Modular Action on Robertson-Walker Space-Times [PDF]
, 2000 A novel method of transplanting algebras of observables from de Sitter space to a large class of Robertson-Walker space-times is exhibited. It allows one to establish the existence of an abundance of local nets on these spaces which comply with a ...

New Dimensions for Wound Strings: The Modular Transformation of Geometry to Topology [PDF]
, 2006 We show, using a theorem of Milnor and Margulis, that string theory on compact negatively curved spaces grows new effective dimensions as the space shrinks, generalizing and contextualizing the results in hep-th/0510044. Milnor's theorem relates negative

Dynamics of compact quantum metric spaces
, 2020 We provide a detailed study of actions of the integers on compact quantum metric spaces, which includes general criteria ensuring that the associated crossed product algebra is again a compact quantum metric space in a natural way.

Modular curves, C* algebras, and chaotic cosmology [PDF]
, 2003 We make some brief remarks on the relation of the mixmaster universe model of chaotic cosmology to the geometry of modular curves and to noncommutative geometry.

Modularity, Quaternion-Kahler spaces and Mirror Symmetry
, 2013 We provide an explicit twistorial construction of quaternion-Kahler manifolds obtained by deformation of c-map spaces and carrying an isometric action of the modular group SL(2,Z).

Asymptotically Hilbertian Modular Banach Spaces: Examples of Uncountable Categoricity
, 2016 We give a criterion ensuring that the elementary class of a modular Banach space E (that is, the class of Banach spaces, some ultrapower of which is linearly isometric to an ultrapower of E) consists of all direct sums E\oplus_m H, where H is an ...

A walk in the noncommutative garden [PDF]
, 2006 This text is written for the volume of the school/conference "Noncommutative Geometry 2005" held at IPM Tehran. It gives a survey of methods and results in noncommutative geometry, based on a discussion of significant examples of noncommutative spaces in
