K-Theory from a physical perspective
Gregory Moore
This is an expository paper which aims at explaining a physical point of view on the K-theoretic classification of D-branes. We combine ideas of renormalization group flows between…
The Challenging Cosmic Singularity
Hong Liu, Gregory Moore, Nathan Seiberg
In this talk we discuss the cosmic singularity. We motivate the need to correct general relativity in the study of singularities, and mention the kind of corrections provided by st…
On Decay of K-theory
Emil J. Martinec, Gregory Moore
Closed string tachyon condensation resolves the singularities of nonsupersymmetric orbifolds, however the resolved space typically has fewer D-brane charges than that of the orbifo…
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…
Noncommutative Solitons on Orbifolds
Emil J. Martinec, Gregory Moore
In the noncommutative field theory of open strings in a B-field, D-branes arise as solitons described as projection operators or partial isometries in a algebra. We discuss h…
Remarks on Tachyon Condensation in Superstring Field Theory
David Kutasov, Marcos Marino, Gregory Moore
We generalize recent results on tachyon condensation in boundary string field theory to the superstring.
