N $$ \mathcal{N} $$ = 2 Conformal SYM theories at large N $$ \mathcal{N} $$
Journal of High Energy Physics, 2020 We consider a class of N $$ \mathcal{N} $$ = 2 conformal SU(N) SYM theories in four dimensions with matter in the fundamental, two-index symmetric and anti-symmetric representations, and study the corresponding matrix model provided by localization on a ...

Overlaps and fermionic dualities for integrable super spin chains
Journal of High Energy Physics, 2021 The psu 2 2 4 $$ \mathfrak{psu}\left(2,\left.2\right|4\right) $$ integrable super spin chain underlying the AdS/CFT correspondence has integrable boundary states which describe set-ups where k D3-branes get dissolved in a probe D5-brane. Overlaps between

Image space formalism of convolutional neural networks for k‐space interpolation
Magnetic Resonance in Medicine, EarlyView.Abstract Purpose Noise resilience in image reconstructions by scan‐specific robust artificial neural networks for k‐space interpolation (RAKI) is linked to nonlinear activations in k‐space. To gain a deeper understanding of this relationship, an image space formalism of RAKI is introduced for analyzing noise propagation analytically, identifying and ...

Bk spin vertex models and quantum algebras
Nuclear Physics B, 2020 We construct new solvable vertex models based on the spin representation of the Lie algebra Bk. We use these models to study the algebraic structure underlying such vertex theories.

Journal of High Energy Physics, 2021 Starting from type IIB string theory on an ADE singularity, the (2, 0) little string arises when one takes the string coupling g s to 0. In this setup, we give a unified description of the codimension-two defects of the little string, labeled by a simple

Optimal Control Applications and Methods, EarlyView.Enhanced Cuckoo Search for Model Order Reduction ABSTRACT This article presents a critical review of classical and modern pole clustering techniques for model order reduction in high‐order systems. It highlights key limitations and common pitfalls encountered in traditional approaches, especially when extended to Multi‐Input Multi‐Output (MIMO) systems.

On the structure of symmetric self-dual Lie algebras
, 1995 A finite-dimensional Lie algebra is called (symmetric) self-dual, if it possesses an invariant nondegenerate (symmetric) bilinear form. Symmetric self-dual Lie algebras have been studied by Medina and Revoy, who have proven a very useful theorem about ...

Fortschritte der Physik, EarlyView.Abstract The unification of conformal and fuzzy gravities with internal interactions is based on the facts that i) the tangent group of a curved manifold and the manifold itself do not necessarily have the same dimensions and ii) both gravitational theories considered here have been formulated in a gauge theoretic way.

More on pure gravity with a negative cosmological constant
Journal of High Energy Physics, 2023 We identify an ambiguity in the Chern-Simons formulation of three-dimensional gravity with negative cosmological constant that originates in an outer automorphism of the Lie algebra sl $$ \mathfrak{sl} $$ (2, ℝ).
