Homomorphisms of planar $(m, n)$ -colored-mixed graphs to planar targets

Fabien Jacques, Pascal Ochem

An $(m, n)$ -colored-mixed graph $G = (V, A_{1}, A_{2}, \dots, A_{m}, E_{1}, E_{2}, \dots, E_{n})$ is a graph having $m$ colors of arcs and $n$ colors of edges. We do not allow two arcs or edges…

Nice formulas, $x y x$ -formulas, and palindrome patterns

Pascal Ochem, Matthieu Rosenfeld

We characterize the formulas that are avoided by every $α$ -free word for some $α > 1$ . We study the avoidability index of formulas whose fragments are of the form $X Y X$ . The largest…
