Bounds on some energy-like invariants of corona and edge corona of graphs
Notes on Number Theory and Discrete Mathematics, 2022 The Laplacian-energy-like invariant of a finite simple graph is the sum of square roots of all its Laplacian eigenvalues and the incidence energy is the sum of square roots of all its signless Laplacian eigenvalues.

O(N) Sigma Model as a Three Dimensional Conformal Field Theory [PDF]
, 1994 We study a three dimensional conformal field theory in terms of its partition function on arbitrary curved spaces. The large $N$ limit of the nonlinear sigma model at the non-trivial fixed point is shown to be an example of a conformal field theory ...

Matrix Bases for Star Products: a Review [PDF]
, 2014 We review the matrix bases for a family of noncommutative $\star$ products based on a Weyl map. These products include the Moyal product, as well as the Wick-Voros products and other translation invariant ones.

Reciprocal distance Laplacian spectral properties double stars and their complements
Carpathian Mathematical Publications, 2023 Several matrices are associated with graphs in order to study their properties. In such a study, researchers are interested in the spectra of the matrix under consideration, therefore, the properties are called spectral properties, with reference to the ...

Gauge invariance and mass gap in (2+1)-dimensional Yang-Mills theory [PDF]
, 1996 In terms of a gauge-invariant matrix parametrization of the fields, we give an analysis of how the mass gap could arise in non-Abelian gauge theories in two spatial dimensions.Comment: 10 pages, Plain TeX, talk presented at the Workshop on Low ...

Unification Scale, Proton Decay, And Manifolds Of G_2 Holonomy [PDF]
, 2002 Models of particle physics based on manifolds of $G_2$ holonomy are in most respects much more complicated than other string-derived models, but as we show here they do have one simplification: threshold corrections to grand unification are particularly ...

Pointlike Hopf defects in Abelian projections [PDF]
, 2000 We present a new kind of defect in Abelian Projections, stemming from pointlike zeros of second order. The corresponding topological quantity is the Hopf invariant pi_3(S^2) (rather than the winding number pi_2(S^2) for magnetic monopoles).

Parabolic theory of the discrete p-Laplace operator [PDF]
, 2013 We study the discrete version of the $p$-Laplacian. Based on its variational properties we discuss some features of the associated parabolic problem.

Eisenstein Series and String Thresholds [PDF]
, 1998 We investigate the relevance of Eisenstein series for representing certain $G(Z)$-invariant string theory amplitudes which receive corrections from BPS states only. $G(Z)$ may stand for any of the mapping class, T-duality and U-duality groups $Sl(d,Z)$, $

On the spectra of a new duplication based corona of graphs
, 2021 : In this paper we introduce a new corona-type product of graphs namely duplication corresponding corona. Here we mainly determine the adjacency, Laplacian and signless Laplacian spectra of the new graph product.
