IET Image Processing, Volume 18, Issue 14, Page 4760-4777, 11 December 2024.The proposed method enables the consideration of more complex affinity relationship beyond pairwise while keeping computational demands within a manageable threshold. A factorization for global affinity matrix of any k graphs is proposed. The proposed method unifies existing multi‐graph matching methods and opens new avenues for future studies ...

A proposal for 0 extended supersymmetry in integrable systems [PDF]
Physics Letters B, 1996 Utilizing techniques suggested by the recently obtained construction of off-shell spinning particles, we propose the arbitrary $N$-extension of supersymmetry for the KdV system. It is further suggested that the ${\aleph}_0$ extension for the SKdV system provides a paradigm for {\underline {all}} supersymmetric completely integrable systems.

Asymptotic Behavior of Saxion–Axion System in Stringy Quintessence Model
Fortschritte der Physik, Volume 72, Issue 11, November 2024.Abstract The late time behavior of the slow‐roll parameter in the stringy quintessence model is studied when axion as well as saxion are allowed to move. Even though the potential is independent of the axion at tree level, the axion can move through its coupling to the saxion and the background geometry.

Supergravity and local extended supersymmetry
Physics Letters B, 1977 Abstract We consider the possibility of having supergravity theories with several (N > 2) Majorana spin 3 2 gauge fields. From the spinor dual model one can infer the existence of these theories with (Yang-Mills) matter coupling up to N = 4 spin 3 2 gauge fields. In the present note we construct the simplest of these theories, i.e. pure

de Sitter State in Heterotic String Theory
Fortschritte der Physik, Volume 72, Issue 11, November 2024.Abstract Recent no‐go theorems have ruled out four‐dimensional classical de Sitter vacua in heterotic string theory. On the other hand, the absence of a well‐defined Wilsonian effective action and other related phenomena also appear to rule out such time‐dependent vacua with de Sitter isometries, even in the presence of quantum corrections.

Interface‐Interactive Nanoarchitectonics: Solid and/or Liquid
ChemPhysChem, Volume 25, Issue 19, October 1, 2024.As the concept of post‐nanotechnology, the new concept of nanoarchitectonics is now emerging. However, such structural control and fabrication are not always easy. A realistic methodology to control such structures is the use of interfacial environments. In this review paper, under the title of interface‐interactive nanoarchitectonics, several examples

Perturbative higher-derivative terms in N $$ \mathcal{N} $$ = 6 asymmetric orbifolds
Journal of High Energy Physics, 2022 We analyse the perturbative four-point amplitudes in the simplest string theory examples of T-fold backgrounds, which enjoy N $$ \mathcal{N} $$ = 6 supersymmetries in four dimensions.

Moduli anomalies and local terms in the operator product expansion
Journal of High Energy Physics, 2018 Local terms in the Operator Product Expansion in Superconformal Theories with extended supersymmetry are identified. Assuming a factorized structure for these terms their contributions are discussed.

Journal of the London Mathematical Society, Volume 109, Issue 6, June 2024.Abstract We construct a family of solvable lattice models whose partition functions include p$p$‐adic Whittaker functions for general linear groups from two very different sources: from Iwahori‐fixed vectors and from metaplectic covers. Interpolating between them by Drinfeld twisting, we uncover unexpected relationships between Iwahori and metaplectic ...

Supersymmetric many-body Euler–Calogero–Moser model
Physics Letters B, 2019 We explicitly construct a supersymmetric so(n) spin-Calogero model with an arbitrary even number N of supersymmetries. It features 12Nn(n+1) rather than Nn fermionic coordinates and a very simple structure of the supercharges and the Hamiltonian.
