On Semisymmetric Cubic Graphs of Order 20p2, p Prime

open access: yesDiscussiones Mathematicae Graph Theory, 2021
A simple graph is called semisymmetric if it is regular and edge-transitive but not vertex-transitive. Let p be an arbitrary prime. Folkman proved [Regular line-symmetric graphs, J. Combin. Theory 3 (1967) 215–232] that there is no semisymmetric graph of

The crucial importance of the $t_{2g}$--$e_g$ hybridization in transition metal oxides [PDF]

open access: yes, 2007
We studied the influence of the trigonal distortion of the regular octahedron along the (111) direction, found in the $\rm CoO_2$ layers. Under such a distortion the $t_{2g}$ orbitals split into one $a_{1g}$ and two degenerated $e_g^\prime$ orbitals.

Erdos Conjecture I. [PDF]

open access: yes, 2000
In this short paper I show how it is related to other famous unsolved problems in prime number theory. In order to do this, I formulate the main hypothetical result of this paper - a useful upper bound conjecture (Conjecture 3.), describing one aspect of

Zero-jettiness resummation for top-quark pair production at the LHC

open access: yesJournal of High Energy Physics, 2022
We study the resummation of the 0-jettiness resolution variable T $$ \mathcal{T} $$ 0 for the top-quark pair production process in hadronic collisions.

The lattice of primary ideals of orders in quadratic number fields [PDF]

open access: yes, 2016
Let $O$ be an order in a quadratic number field $K$ with ring of integers $D$, such that the conductor $\mathfrak F = f D$ is a prime ideal of $O$, where $f\in\mathbb Z$ is a prime. We give a complete description of the $\mathfrak F$-primary ideals of $O$

NNLO+PS W + W − production using jet veto resummation at NNLL′

open access: yesJournal of High Energy Physics, 2023
We construct a novel event generator for the process pp → ℓ − ν ¯ ℓ ℓ ′ + ν ℓ ′ $$ pp\to {\ell}^{-}{\overline{\nu}}_{\ell }{\ell^{\prime}}^{+}{\nu}_{\ell^{\prime }} $$ , which matches fixed-order predictions at next-to-next-to-leading order in the strong

Entire and meromorphic solutions for systems of the differential difference equations

open access: yesDemonstratio Mathematica, 2022
With the help of the Nevanlinna theory of meromorphic functions, the purpose of this article is to describe the existence and the forms of transcendental entire and meromorphic solutions for several systems of the quadratic trinomial functional equations:

Recognition of the Simple Groups 2D8((2n)2)

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2019
One of the important problems in finite groups theory is group characterization by specific property. Properties, such as element orders, set of elements with the same order, the largest element order, etc.

Centralizers in good groups are good [PDF]

open access: yes, 2014
We modify the transchromatic character maps to land in a faithfully flat extension of Morava E-theory. Our construction makes use of the interaction between topological and algebraic localization and completion.

Minor Prime Factorization for n-D Polynomial Matrices over Arbitrary Coefficient Field

open access: yesComplexity, 2018
In this paper, we investigate two classes of multivariate (n-D) polynomial matrices whose coefficient field is arbitrary and the greatest common divisor of maximal order minors satisfy certain condition.
