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 ...

All partial breakings in N=2 $$ \mathcal{N}=2 $$ supergravity with a single hypermultiplet
Journal of High Energy Physics, 2018 We consider partial supersymmetry breaking in N=2 $$ \mathcal{N}=2 $$ supergravity coupled to a single vector and a single hypermultiplet. This breaking pattern is in principle possible if the quaternion-Kähler space of the hypermultiplet admits (at ...

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.

Predicting Alignment in a Two Higgs Doublet Model
Proceedings, 2019 We show that a non-abelian global S U ( 2 ) R R-symmetry acting on the quartic part of the two Higgs Doublet Model leads, at tree-level, to an automatic alignment without decoupling.

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

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 ...

The anti-de Sitter supergeometry revisited
Journal of High Energy PhysicsIn a supergravity framework, the N $$ \mathcal{N} $$ -extended anti-de Sitter (AdS) superspace in four spacetime dimensions, AdS 4 4 N $$ {\textrm{AdS}}^{4\left|4\mathcal{N}\right.} $$ , is a maximally symmetric background that is described by a curved ...
