Orthogonal polynomial method and odd vertices in matrix models [PDF]

open access: yes, 1999
We show how to use the method of orthogonal polynomials for integrating, in the planar approximation, the partition function of one-matrix models with a potential with even or odd vertices, or any combination of them.Comment: 13 pages, 3 Postscript ...

SYK Model with global symmetries in the double scaling limit

open access: yesJournal of High Energy Physics, 2023
We discuss the double scaling limit of the SYK model with global symmetries. We develop the chord diagram techniques to compute the moments of the Hamiltonian and the two point function in the presence of arbitrary chemical potential.

Efficient Distortion Mitigation and Partition Reduction in Mapping Global Geodata: Dual Orthogonal Equidistant Cylindrical Projection Approach

open access: yesISPRS International Journal of Geo-Information, 2023
The rapid growth in Earth’s global geospatial data necessitates an efficient system for organizing the data, facilitating data fusion from diverse sources, and promoting interoperability.

Unquenched QCD dirac operator spectra at nonzero baryon chemical potential [PDF]

open access: yes, 2004
The microscopic spectral density of the QCD Dirac operator at nonzero baryon chemical potential for an arbitrary number of quark flavors was derived recently from a random matrix model with the global symmetries of QCD.

Improved Local Ternary Patterns for Automatic Target Recognition in Infrared Imagery

open access: yesSensors, 2015
This paper presents an improved local ternary pattern (LTP) for automatic target recognition (ATR) in infrared imagery. Firstly, a robust LTP (RLTP) scheme is proposed to overcome the limitation of the original LTP for achieving the invariance with ...

Spaces of states of the two-dimensional $O(n)$ and Potts models

open access: yesSciPost Physics, 2023
We determine the spaces of states of the two-dimensional $O(n)$ and $Q$-state Potts models with generic parameters $n,Q\in \mathbb{C}$ as representations of their known symmetry algebras.

Multiscale Partition of Unity [PDF]

open access: yes, 2013
We introduce a new Partition of Unity Method for the numerical homogenization of elliptic partial differential equations with arbitrarily rough coefficients. We do not restrict to a particular ansatz space or the existence of a finite element mesh.

ORTHOGONAL PARTITIONS OF THE 6times6 LATIN SQUARES [PDF]

open access: yesAnnals of Eugenics, 1946
The articles published by the Annals of Eugenics (1925–1954) have been made available online as an historical archive intended for scholarly use. The work of eugenicists was often pervaded by prejudice against racial, ethnic and disabled groups. The online publication of this material for scholarly research purposes is not an endorsement of those views

Tensor invariants for certain subgroups of the orthogonal group [PDF]

open access: yes, 2012
Let V be an n-dimensional vector space and let On be the orthogonal group. Motivated by a question of B. Szegedy (B. Szegedy, Edge coloring models and reflection positivity, Journal of the American Mathematical Society Volume 20, Number 4, 2007), about ...
