Tiling edge-ordered graphs with monotone paths and other structures

Igor Araujo, Simón Piga, Andrew Treglown +1

Given graphs $F$ and $G$ , a perfect $F$ -tiling in $G$ is a collection of vertex-disjoint copies of $F$ in $G$ that together cover all the vertices in $G$ . The study of the minimum…

Triangle Percolation on the Grid

Igor Araujo, Bryce Frederickson, Robert A. Krueger +5

We consider a geometric percolation process partially motivated by recent work of Hejda and Kala. Specifically, we start with an initial set $X \subseteq Z^{2}$ , and then it…

Realizable Standard Young Tableaux

Igor Araujo, Alexander E. Black, Amanda Burcroff +3

Given two vectors $u$ and $v$ , their outer sum is given by the matrix $A$ with entries $A_{ij} = u_{i} + v_{j}$ . If the entries of $u$ and $v$ are increasing and sufficiently gener…
