On avoidance of V- and ^-patterns in permutations.

Ars Comb., 2010
We study V- and ^-patterns which generalize valleys and peaks, as well as increasing and decreasing runs, in permutations. A complete classi¯cation of permutations (multi)-avoiding V- and ¤-patterns of length 4 is given. We also establish a connection between restricted permutations and matchings in the coronas of complete graphs.

Edge colorings avoiding patterns

European Journal of Combinatorics
Assume a set \(V\subseteq \mathbb{R}^2\) of order \(n\), where no three points are collinear, is given. A visibility-blocking set is a set \(B\) disjoint from \(V\) such that every segment with endpoints in \(V\) contains a point from \(B\). Here, \(b(V)\) is the minimum cardinality of \(B\) for given \(V\), while \(b(n)\) is the minimum of \(b(V ...
