On the total versions of 1-2-3-conjecture for graphs and hypergraphs

Akbar Davoodi, Leila Maherani

In 2004, Karoński, Łuczak and Thomason proposed $1$ - $2$ - $3$ -conjecture: For every nice graph $G$ there is an edge weighting function $w : E (G) \to {1, 2, 3}$ such that the in…

On a Conjecture of Erd\H os on Size Ramsey Number of Star Forests

Akbar Davoodi, Ramin Javadi, Azam Kamranian +1

Given graphs $F_{1}, F_{2}$ and $G$ , we say that $G$ is Ramsey for $(F_{1}, F_{2})$ and we write $G \to (F_{1}, F_{2})$ , if for every edge coloring of $G$ by red and blue, there is eithe…

On Clique Coverings of Complete Multipartite Graphs

Akbar Davoodi, Dániel Gerbner, Abhishek Methuku +1

A clique covering of a graph $G$ is a set of cliques of $G$ such that any edge of $G$ is contained in one of these cliques, and the weight of a clique covering is the sum of the si…
