On the periodic decompositions of multidimensional configurations
Pyry Herva, Jarkko Kari
We consider -dimensional configurations, that is, colorings of the -dimensional integer grid with finitely many colors. Moreover, we interpret the colors as in…

Periodicity and local complexity of Delone sets
Pyry Herva, Jarkko Kari
We study complexity and periodicity of Delone sets by applying an algebraic approach to multidimensional symbolic dynamics. In this algebraic approach, -configuration…

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…
