F-theory vacua and α′-corrections

Journal of High Energy Physics, 2020
In this work we analyze F-theory and Type IIB orientifold compactifications to study α′-corrections to the four-dimensional, N $$ \mathcal{N} $$ = 1 effective actions.

Case-Based Statistical Learning: A Non-Parametric Implementation With a Conditional-Error Rate SVM

IEEE Access, 2017
Machine learning has been successfully applied to many areas of science and engineering. Some examples include time series prediction, optical character recognition, signal and image classification in biomedical applications for diagnosis and prognosis ...

Supersymmetry breaking in M-theory [PDF]

, 1997
We describe the breaking of supersymmetry in M-theory by coordinate dependent (Scherk-Schwarz) compactification of the eleventh dimension. Supersymmetry is spontaneously broken in the gravitational and moduli sector and communicated to the observable ...

Nambu Bracket for M Theory [PDF]

, 2010
In this article we give a concise review of recent progress in our understanding of the Lie 3-algebra and their application to the Bagger-Lambert-Gustavsson model describing multiple M2-branes in M theory.Comment: 13 pages, prepared for The Fourth ...

Beyond LLM in M-theory [PDF]

, 2012
The Lin, Lunin, Maldacena (LLM) ansatz in D = 11 supports two independent Killing directions when a general Killing spinor ansatz is considered. Here we show that these directions always commute, identify when the Killing spinors are charged, and show ...

Holographic Superconductivity in M Theory [PDF]

Physical Review Letters, 2009
Using seven-dimensional Sasaki-Einstein spaces we construct solutions of D=11 supergravity that are holographically dual to superconductors in three spacetime dimensions. Our numerical results indicate a new zero temperature solution dual to a quantum critical point.

TIME AND M-THEORY

International Journal of Modern Physics A, 2007
We review our recent proposal for a background-independent formulation of a holographic theory of quantum gravity. The present paper incorporates the necessary background material on geometry of canonical quantum theory, holography and space–time thermodynamics, Matrix theory, as well as our specific proposal for a dynamical theory of geometric quantum

Five-dimensional non-Lorentzian conformal field theories and their relation to six-dimensions

Journal of High Energy Physics, 2021
We study correlation functions in five-dimensional non-Lorentzian theories with an SU(1, 3) conformal symmetry. Examples of such theories have recently been obtained as Ω-deformed Yang-Mills Lagrangians arising from a null reduction of six-dimensional ...

Research on the Shadow Economy and Assessment of Its Scale: On the Example of Kazakhstan

Economies
The manuscript aims to assess the scale of shadow economic processes within the non-observed economy, focusing on the self-employment sector, which is insufficiently reflected in national statistics.
