Strongly Cancellative and Recovering Sets on Lattices

Hoda Bidkhori, ShinnYih Huang


We use information theory to study recovering sets ${\mathbf{R}}_L$ and strongly cancellative sets ${\mathbf{C}}_L$ on different lattices. These sets are special classes of recovering pairs and cancellative sets previously discussed in the papers of Simonyi, Frankl, and Füredi. We mainly focus on the lattices $B_n$ and $D_{l}^{k}$. Specifically, we find upper bounds and constructions for the sets ${\mathbf{R}}_{B_n}$, ${\mathbf{C}}_{B_n}$, and ${\mathbf{C}}_{D_{l}^{k}}$.
