Vertex-monochromatic connectivity of strong digraphs

Diego González-Moreno, Mucuy-kak Guevara, Juan José Montellano-Ballesteros

A vertex coloring of a strong digraph $D$ is a \emph{strong vertex-monochromatic connection coloring (SVMC-coloring)} if for every pair $u, v$ of vertices in $D$ there exists an $(…

Advances on the Conjecture of Erdős-Sós for spiders

Camino Balbuena, Mucuy-Kak Guevara, José R. Portillo +1

- A hamiltonian graph $G$ verifying $e (G) > n (k - 1) /2$ %with a vertex of degree greater or equal than $k$ contains any $k$ -spider. - If $G$ is a graph with average degree $\bar{d} > k…
