Antimagic labelings of regular bipartite graphs: An application of the Marriage Theorem [PDF]

open access: yes, 2020
A labeling of a graph is a bijection from E(G) to the set {1, 2, . . . , |E(G)|}. A labeling is antimagic if for any distinct vertices u and v, the sum of the labels on edges incident to u is different from the sum of the labels on edges incident to v ...

Rainbow eulerian multidigraphs and the product of cycles [PDF]

open access: yes, 2014
An arc colored eulerian multidigraph with $l$ colors is rainbow eulerian if there is an eulerian circuit in which a sequence of $l$ colors repeats. The digraph product that refers the title was introduced by Figueroa-Centeno et al. as follows: let $D$ be

Site-specific vibrational spectral signatures of water molecules in the magic H3O+(H2O)20 and Cs+(H2O)20 clusters [PDF]

open access: yes, 2014
Theoretical models of proton hydration with tens of water molecules indicate that the excess proton is embedded on the surface of clathrate-like cage structures with one or two water molecules in the interior.

Labeling Generating Matrices [PDF]

open access: yes, 2006
This paper is mainly devoted to generate (special)(super) edge-magic labelings of graphs using matrices. Matrices are used in order to find lower bounds for the number of non-isomorphic (special)(super) edge-magic labelings of certain types of graphs.

Distance magic-type and distance antimagic-type labelings of graphs [PDF]

open access: yes, 2017
Generally speaking, a distance magic-type labeling of a graph G of order n is a bijection f from the vertex set of the graph to the first n natural numbers or to the elements of a group of order n, with the property that the weight of each vertex is the ...

Team assisted individualization: enhancing students’ conjecturing skills in statistics and probability [PDF]

open access: yes
Many students struggle to understand mathematical concepts, leading to inadequate conjecturing skills. This study investigates the effectiveness of team assisted individualization (TAI), a cooperative learning approach, in improving these skills in ...

Robot Positioning Using Torus Packing for Multisets [PDF]

open access: yes
We consider the design of a positioning system where a robot determines its position from local observations. This is a well-studied problem of considerable practical importance and mathematical interest.

Magic coverings and the Kronecker product [PDF]

open access: yes, 2009
In this paper we study a relationship existing among (super) magic coverings and the well known Kronecker product of matrices. We also introduce the concept of Zn–property for digraphs in order to study this relation mentioned before.
