TASI 2003 Lectures on Anomalies
Jeffrey A. Harvey
These lecture notes review the structure of anomalies and present some of their applications in field theory, string theory and M theory. They expand on material presented at the T…
Worldsheet Instanton Corrections to the Kaluza-Klein Monopole
Jeffrey A. Harvey, Steuard Jensen
The Kaluza-Klein monopole is a well known object in both gravity and string theory, related by T-duality to a "smeared" NS5-brane which retains the isometry around the duality circ…
Localized Tachyons and RG Flows
Jeffrey A. Harvey, David Kutasov, Emil J. Martinec +1
We study condensation of closed string tachyons living on defects, such as orbifold fixed planes and Neveu-Schwarz fivebranes. We argue that the high energy density of localized st…
Topology of the Gauge Group in Noncommutative Gauge Theory
Jeffrey A. Harvey
I argue that the gauge group of noncommutative gauge theory consists of maps into unitary operators on Hilbert space of the form with compact. Some implications of this…
On the relevance of tachyons
J. A. Harvey, D. Kutasov, E. J. Martinec
We study condensation of open string tachyons using renormalization group flow in the worldsheet field theory. This approach leads to a simple picture of the physics of the nontriv…
S-Duality and the Spectrum of Magnetic Monopoles in Heterotic String Theory
J. P. Gauntlett, J. A. Harvey
We discuss the predictions of S-duality for the monopole spectrum of four-dimensional heterotic string theory resulting from toroidal compactification. We discuss in detail the spe…
