Closed Strings in Misner Space: A Toy Model for a Big Bounce?ure, we review the semi-classical propagation of closed strings in this background, with a particular emphasis on the twisted sectors of the orbifold. Tree-level scattering amplitudes and the one-loop vacuum amplitude are also discussed.CROAK 发表于 2025-3-23 17:34:19
Semiclassical Strings and AdS/CFTproach, in which similar 2d sigma model actions appear from the .. × .. string action and from the integrable spin chain Hamiltonian representing the N=4 super Yang-Mills dilatation operator. We consider mostly the leading-order terms in the energies/anomalous dimensions which match but comment also on higher-order corrections.MIRTH 发表于 2025-3-23 19:51:11

Chaotic Cascades for D-Branes on Sigularities are sometimes chaotic and exhibit duality walls. We construct supergravity solutions dual to logarithmic flows for these theories. We make new observations about a surface of conformal theories and more complicated supergravity solutions.死亡率 发表于 2025-3-24 06:24:04
= 1 Gauge Theory Effective Superpotentialsce with matrix models and two proofs of this are discussed. By considering the case with matter transforming in the fundamental representation, a Wilsonian derivation of the Veneziano-Yankielowicz effective superpotential for a pure gauge theory is given using the generalized Konishi anomaly.Gratulate 发表于 2025-3-24 06:44:52
Gromov-Witten Theory and Automorphic Formsic properties of their generating function (GW potential). The plan is to interpolate between Morozov’s and Dijkgraaf’s lectures, i.e. between KdV hierarchies (or their solutions as .-functions) and topological strings (or correlators of operators on a worldsheet).外貌 发表于 2025-3-24 12:16:11
Quantization of Holomorphic Forms and , = 1 Supersymmetry on Special Manifoldsds twisted supersymmetric theories. For Kähler manifolds in four dimensions, our topological model is related to . = 1 Super Yang—Mills theory. Extended supersymmetries are recovered by considering the coupling with chiral multiplets.Digitalis 发表于 2025-3-24 15:50:08
