Quantum Field Theory and Differential Geometry

open access: yes, 2008
We introduce the historical development and physical idea behind topological Yang-Mills theory and explain how a physical framework describing subatomic physics can be used as a tool to study differential geometry.

Rational points on K3 surfaces and derived equivalence [PDF]

open access: yes, 2015
We study K3 surfaces over non-closed fields and relate the notion of derived equivalence to arithmetic problems.Comment: 30 ...

Spacetime Reduction of Large N Flavor Models: A Fundamental Theory of Emergent Local Geometry?

open access: yes, 2005
We introduce a novel spacetime reduction procedure for the fields of a supergravity-Yang-Mills theory in generic curved spacetime background, and with large N flavor group, to linearized forms on an infinitesimal patch of local tangent space at a point ...

Conformal Symmetry and Universal Properties of Quantum Hall States

open access: yes, 1992
The low-lying excitations of a quantum Hall state on a disk geometry are edge excitations. Their dynamics is governed by a conformal field theory on the cylinder defined by the disk boundary and the time variable. We give a simple and detailed derivation

A comparison between obstructions to local-global principles over semiglobal fields [PDF]

open access: yes, 2020
We consider local-global principles for rational points on varieties, in particular torsors, over one-variable function fields over complete discretely valued fields.

Localized tachyons in C^3/Z_N

open access: yes, 2004
We study the condensation of localized closed string tachyons in C^3/Z_N nonsupersymmetric noncompact orbifold singularities via renormalization group flows that preserve supersymmetry in the worldsheet conformal field theory and their interrelations ...

Deformations of WZW models

open access: yes, 2003
Current-current deformations for WZW models of semisimple compact groups are discussed in a sigma model approach. We start with the abelian rank one group U(1).

Noncommutative Geometry, Extended W(infty) Algebra and Grassmannian Solitons in Multicomponent Quantum Hall Systems

open access: yes, 2002
Noncommutative geometry governs the physics of quantum Hall (QH) effects. We introduce the Weyl ordering of the second quantized density operator to explore the dynamics of electrons in the lowest Landau level. We analyze QH systems made of $N$-component

Poincaré duality in Hochschild (co)homology [PDF]

open access: yes, 2006
These are notes on van den Bergh’s analogue of Poincar´e duality in Hochschild (co)homology [VdB98]. They are based on survey talks that I gave in 2006 in G¨ottingen, Cambridge and Warsaw and consist of an elementary explanation of the proof in terms ...

A new kind of McKay correspondence from non-Abelian gauge theories

open access: yes, 2001
The boundary chiral ring of a 2d gauged linear sigma model on a K\"ahler manifold $X$ classifies the topological D-brane sectors and the massless open strings between them.
