Optimal local identifying and local locating-dominating codes
Pyry Herva, Tero Laihonen, Tuomo Lehtilä
We introduce two new classes of covering codes in graphs for every positive integer . These new codes are called local -identifying and local -locating-dominating codes an…

On forced periodicity of perfect colorings
Pyry Herva, Jarkko Kari
We study forced periodicity of two-dimensional configurations under certain constraints and use an algebraic approach to multidimensional symbolic dynamics in which -dimensional…

On perfect coverings of two-dimensional grids
Elias Heikkilä, Pyry Herva, Jarkko Kari
We study perfect multiple coverings in translation invariant graphs with vertex set using an algebraic approach. In this approach we consider any such covering as a…
