A regular cover of a connected graph is called dihedral ifits transformation group is dihedral. In this paper, the authors clas-sify all dihedral coverings of the Heawood graph whose fibre-preservingautomorphism subgroups act edge-transitively.

A Hamiltonian graph is 2-factor Hamiltonian (2FH) if each of its 2-factors is a Hamiltonian cycle. A similar, but weaker, property is the Perfect-Matching-Hamiltonian property (PMH-property): a graph admitting a perfect matching is said to have this prope... see more

Suppose G=(V,E) is a graph with the vertex set V(G) and edge set E(G) we defined a labeling f:V?E?{1,2,…,k} to be an edge irregular total k-labeling of graph G if for every two different edge e and f there is wt(e)?wt(f). The minimum k for which the graph... see more

This document shows the difficulties identified in a group of 76 students from sixth to ninth grade of a private educational institution whose training emphasis is the teaching of Natural Sciences. A questionnaire was applied to them in which there were f... see more

Along with the rapid development of information technology today, multimedia has an important role in the field of education. Studying the solar system is very important, especially for elementary school children because it is very closely related to othe... see more
