AdS5×S(5) mirror model as a string sigma model. [PDF]

open access: yesPhysical Review Letters, 2014
Doing a double Wick rotation in the world sheet theory of the light cone AdS5×S(5) superstring results in an inequivalent, so-called mirror theory that plays a central role in the field of integrability in the AdS-CFT correspondence.

Higher-genus wall-crossing in the gauged linear sigma model [PDF]

open access: yesDuke mathematical journal, 2017
We introduce a technique for proving all-genus wall-crossing formulas in the gauged linear sigma model as the stability parameter varies, without assuming factorization properties of the virtual class.

Geodesics on Calabi-Yau manifolds and winding states in nonlinear sigma models

open access: yesFrontiers in Physics, 2013
We conjecture that a non-flat D-real-dimensional compact Calabi-Yau manifold, such as a quintic hypersurface with D=6, or a K3 manifold with D=4, has locally length minimizing closed geodesics, and that the number of these with length less than L grows ...

Renormalization of supersymmetric Lifshitz sigma models

open access: yesJournal of High Energy Physics, 2023
We study the renormalization of an N $$ \mathcal{N} $$ = 1 supersymmetric Lifshitz sigma model in three dimensions. The sigma model exhibits worldvolume anisotropy in space and time around the high-energy z = 2 Lifshitz point, such that the worldvolume ...

The Sierpinski Object in the Scott Realizability Topos [PDF]

open access: yesLogical Methods in Computer Science, 2020
We study the Sierpinski object $\Sigma$ in the realizability topos based on Scott's graph model of the $\lambda$-calculus. Our starting observation is that the object of realizers in this topos is the exponential $\Sigma ^N$, where $N$ is the natural ...

Analiza tedenske umrljivosti starostnikov: primerjava med Slovenijo in državami članicami EU27 (= Analysis of weekly mortality of seniors: a comparison between Slovenia and the member states of the EU27) [PDF]

open access: yesGeodetski Vestnik, 2022
We analysed data on the weekly mortality of seniors aged 65 and older in the member states of the EU27. We aimed to model normal mortality in the time before covid-19 and use this model to analyse the deviations of true values from model predictions in ...

Tools for evaluating the performance of HbA1c analyzer: Sigma Metric and Quality Goal Index Ratio

open access: yesInternational Journal of Medical Biochemistry, 2022
INTRODUCTION: Sigma metric model is one of the most popular quality management system tools used for Six Sigma process improvement. This model provides three features that improve the results: low inaccuracy, less deviation, and correct performance of ...

Sigma-model symmetry in orientifold models [PDF]

open access: yesJournal of High Energy Physics, 2000
We investigate in the simplest compact D=4 N=1 Type IIB orientifold models the sigma-model symmetry suggested by the proposed duality of these models to heterotic orbifold vacua. This symmetry is known to be present at the classical level, and is associated to a composite connection involving untwisted moduli in the low-energy supergravity theory.
