"Let Your Characters Tell Their Story": A Dataset for Character-Centric Narrative Understanding
Faeze Brahman, Meng Huang, Oyvind Tafjord +3
When reading a literary piece, readers often make inferences about various characters' roles, personalities, relationships, intents, actions, etc. While humans can readily draw upo…
Fuzzy Funnels: Non-abelian Brane Intersections
Neil R. Constable, Robert C. Myers, Oyvind Tafjord
We discuss dual formulations of D-brane intersections. The duality is between world volume field theories of different dimensionalities which both describe the same D-brane configu…
Non-abelian Brane Intersections
Neil R. Constable, Robert C. Myers, Oyvind Tafjord
We study new solutions of the low-energy equations of motion for the non-abelian D-string. We find a "fuzzy funnel" solution consisting of a noncommutative four-sphere geometry whi…
SUSY and Goliath
Marcus T. Grisaru, Robert C. Myers, Oyvind Tafjord
We investigate the `giant gravitons' of McGreevy, Susskind and Toumbas [hep-th/0003075]. We demonstrate that these are BPS configurations which preserve precisely the same supersym…
The Noncommutative Bion Core
Neil R. Constable, Robert C. Myers, Oyvind Tafjord
We examine noncommutative solutions of the nonabelian theory on the world-volume of N coincident D-strings. These solutions can be interpreted in terms of noncommutative geometry a…
Baryons and Flux Tubes in Confining Gauge Theories from Brane Actions
Curtis G. Callan, Alberto Guijosa, Konstantin G. Savvidy +1
We study baryon configurations in large N non-supersymmetric SU(N) gauge theories, applying the AdS/CFT correspondence. Using the D5-brane worldvolume theory in the near-horizon ge…
Matrix string interactions
Vipul Periwal, Oyvind Tafjord
String configurations have been identified in compactified Matrix theory at vanishing string coupling. We show how the interactions of these strings are determined by the Yang-Mill…
A finite cutoff on the string worldsheet?
Vipul Periwal, Øyvind Tafjord
D-brane backgrounds are specified in closed string theories by holes with appropriate mixed Dirichlet and Neumann boundary conditions on the string worldsheet. As presently stated,…
Mechanism for long Dijkgraaf-Verlinde-Verlinde strings
Vipul Periwal, Oyvind Tafjord
The proposal of Dijkgraaf, Verlinde and Verlinde for the emergence of smooth strings from a supersymmetric U(N) Yang-Mills theory assumes that conjugacy classes in the symmetric gr…
D-brane recoil
Vipul Periwal, Øyvind Tafjord
It is shown that there are logarithmic operators in D-brane backgrounds that lead to infrared divergences in open string loop amplitudes. These divergences can be cancelled by chan…
