Geometries, non-geometries, and fluxes [PDF]

open access: yesAdvances in Theoretical and Mathematical Physics, 2010
Using F-theory/heterotic duality, we describe a framework for analyzing non-geometric T2-fibered heterotic compactifications to six- and four-dimensions. Our results suggest that among T2-fibered heterotic string vacua, the non-geometric compactifications are just as typical as the geometric ones. We also construct four-dimensional solutions which have

E8 geometry [PDF]

open access: yesJournal of High Energy Physics, 2015
We investigate exceptional generalised diffeomorphisms based on E8 (8) in a geometric setting. The transformations include gauge transformations for the dual gravity field. The surprising key result, which allows for a development of a tensor formalism, is that it is possible to define field-dependent transformations containing connection, which are ...

Celestial geometry

open access: yesJournal of High Energy Physics, 2022
Abstract Celestial holography expresses $$ \mathcal{S} $$ S -matrix elements as correlators in a CFT living on the night sky. Poincaré invariance imposes additional selection rules on the allowed positions of operators.

A counterexample to the CFT convexity conjecture

open access: yesJournal of High Energy Physics, 2023
Motivated by the weak gravity conjecture, [Phys. Rev. D 104 (2021) 126005] conjectured that in any CFT, the minimal operator dimension at fixed charge is a convex function of the charge.

Delayed deconfinement and the Hawking-Page transition

open access: yesJournal of High Energy Physics, 2022
We revisit the confinement/deconfinement transition in N $$ \mathcal{N} $$ = 4 super Yang-Mills (SYM) theory and its relation to the Hawking-Page transition in gravity.

Geometry from information geometry [PDF]

open access: yesAIP Conference Proceedings, 2016
We use the method of maximum entropy to model physical space as a curved statistical manifold. It is then natural to use information geometry to explain the geometry of space. We find that the resultant information metric does not describe the full geometry of space but only its conformal geometry -- the geometry up to local changes of scale ...

SPINOR GEOMETRY [PDF]

open access: yesInternational Journal of Modern Physics A, 2012
It has been proposed that quantum mechanics and string theory share a common inner syntax, the relational logic of C. S. Peirce. Along this line of thought we consider the relations represented by spinors. Spinor composition leads to the emergence of Minkowski space–time.

On the relation between mixed Morrey spaces and mixed Morrey double-sequence spaces [PDF]

open access: yesITM Web of Conferences
In this article, we prove that mixed Morrey double-sequence spaces can be realized as a subspace of mixed Morrey spaces. Our proof extends a similar result for discrete Morrey spaces, obtained by Kikianty and Schwanke in 2019.
