Duality of (0,2) string vacua [PDF]
Nuclear Physics B, 1995 We discuss a duality of (0,2) heterotic string vacua which implies that certain pairs of (0,2) Calabi-Yau compactifications on topologically distinct target manifolds yield identical string theories. Some complex structure moduli in one model are interpreted in the dual model as deforming the holomorphic structure of the vacuum gauge bundle (and vice ...

Nuclear Physics B, 2015 Just as string T-duality originates from transforming field equations into Bianchi identities on the string worldsheet, so it has been suggested that M-theory U-dualities originate from transforming field equations into Bianchi identities on the membrane

Strings, T-duality breaking, and nonlocality without the shortest distance [PDF]
, 2006 T-duality of string theory suggests nonlocality manifested as the shortest possible distance. As an alternative, we suggest a nonlocal formulation of string theory that breaks T-duality at the fundamental level and does not require the shortest possible ...

T-duality and high-derivative gravity theories: the BTZ black hole/string paradigm
Journal of High Energy Physics, 2018 We show that the temperature and entropy of a BTZ black hole are invariant under T-duality to next to leading order in M ⋆− 2, M ⋆ being the scale suppressing higher-curvature/derivative terms in the Lagrangian. We work in the framework of a twoparameter

M-Theory (the Theory Formerly Known as Strings) [PDF]
, 1996 Superunification underwent a major paradigm shift in 1984 when eleven-dimensional supergravity was knocked off its pedestal by ten-dimensional superstrings.

On Mathieu moonshine and Gromov-Witten invariants
Journal of High Energy Physics, 2020 We provide further evidence that CY 3 manifolds are involved in an intricate way in Mathieu moonshine, i.e., their Gromov-Witten invariants are related to the expansion coefficients of the twined/twisted-twined elliptic genera of K3.

Torus bundles, automorphisms and T-duality
Journal of High Energy Physics, 2021 We reconsider some older constructions of T-duality, based on automorphisms of the worldsheet operator algebra, in a modern context. It has been long known that at special points in the moduli space of torus compactifications, the target space gauge ...

S-Duality and Cosmological Constant in String Theory [PDF]
, 1996 The S-duality invariance of the equations of motion of four dimensional string effective action with cosmological constant, $\Lambda $, is studied. It is demonstrated that the S-duality symmetry of the field equations are broken for nonzero $\Lambda ...

NONCOMMUTATIVE GEOMETRY, STRINGS AND DUALITY [PDF]
International Journal of Modern Physics B, 2000 In this talk, based on work done in collaboration with G. Landi and R. J. Szabo, I will review how string theory can be considered as a noncommutative geometry based on an algebra of vertex operators. The spectral triple of strings is introduced, and some of the string symmetries, notably target space duality, are discussed in this framework.
