A pedagogical and self-contained introduction to noncommutative quantum field theory is presented, with emphasis on those properties that are intimately tied to string theory and gravity. Topicsâ€¦ (More)

We describe a novel duality symmetry of Î¦2n-theory defined on noncommutative Euclidean space and with noncommuting momentum coordinates. This duality acts on the fields by Fourier transformation andâ€¦ (More)

We estimated the prevalence of fluoroquinolone resistant Escherichia coli in patients undergoing repeat transrectal ultrasound guided prostate needle biopsy and identified high risk groups.â€¦ (More)

A detailed review of recent developments in the topological classification of D-branes in superstring theory is presented. Beginning with a thorough, self-contained introduction to the techniques andâ€¦ (More)

We present the exact solution of a scalar field theory defined with noncommuting position and momentum variables. The model describes charged particles in a uniform magnetic field and with anâ€¦ (More)

This paper comprises the written version of the lectures on string theory delivered at the 31st British Universities Summer School on Theoretical Elementary Particle Physics which was held inâ€¦ (More)

We compute the leading order perturbative correction to the static potential in N = 4 supersymmetric Yang-Mills theory. We show that the perturbative expansion contains infrared logarithms which,â€¦ (More)

We review equivariant localization techniques for the evaluation of Feynman path integrals. We develop systematic geometric methods for studying the semi-classical properties of phase space pathâ€¦ (More)

We describe an algebraic approach to the time-dependent noncommutative geometry of a six-dimensional Cahen-Wallach pp-wave string background supported by a constant Neveu-Schwarz flux, and develop aâ€¦ (More)
