AUTOMORPHISM GROUPS OF MAPS, SURFACES AND SMARANDACHE GEOMETRIES [PDF]

open access: yes, 2005
A combinatorial map is a connected topological graph cellularly embedded in a surface. As a linking of combinatorial configuration with the classical mathematics, it fascinates more and more mathematician’s interesting.

An introduction to Smarandache multi-spaces and mathematical combinatorics [PDF]

open access: yes, 2007
These Smarandache spaces are right theories for objectives by logic. However, the mathematical combinatorics is a combinatorial theory for branches in classical mathematics motivated by a combinatorial speculation.

On Size Bipartite and Tripartite Ramsey Numbers for The Star Forest and Path on 3 Vertices

open access: yesJournal of Mathematical and Fundamental Sciences, 2020
For simple graphs G and H the size multipartite Ramsey number mj(G,H) is the smallest natural number t such that any arbitrary red-blue coloring on the edges of Kjxt contains a red G or a blue H as a subgraph.

Ramsey minimal graphs for a pair of a cycle on four vertices and an arbitrary star

open access: yesElectronic Journal of Graph Theory and Applications, 2022
Let F, G and H be simple graphs. The notation F → (G, H) means that for any red-blue coloring on the edges of graph F, there exists either a red copy of G or a blue copy of H.

On size multipartite Ramsey numbers for stars versus paths and cycles

open access: yesElectronic Journal of Graph Theory and Applications, 2017
Let $K_{l\times t}$ be a complete, balanced, multipartite graph consisting of $l$ partite sets and $t$ vertices in each partite set. For given two graphs $G_1$ and $G_2$, and integer $j\geq 2$, the size multipartite Ramsey number $m_j(G_1,G_2)$ is the ...

A method to construct graphs with certain partition dimension

open access: yesElectronic Journal of Graph Theory and Applications, 2019
In this paper, we propose a method for constructing new graphs from a given graph G so that the resulting graphs have the partition dimension at most one larger than the partition dimension of the graph G.

Modular Irregular Labeling on Double-Star and Friendship Graphs

open access: yesJournal of Mathematics, 2021
A modular irregular graph is a graph that admits a modular irregular labeling. A modular irregular labeling of a graph G of order n is a mapping of the set of edges of the graph to 1,2,…,k such that the weights of all vertices are different.

Combinatorial proofs in mathematics teaching [PDF]

open access: yes, 2022
U ovom diplomskom radu bavimo se kombinatornim dokazima u nastavi matematike. Na početku rada ukratko smo iznijeli povijesni razvoj dokaza. U drugom dijelu rada naveli smo svrhu i potrebu za dokazima unutar nastave matematike; najprije iz učeničke ...
