Two distance memories in desert ants-Modes of interaction. [PDF]
PLoS ONE, 2018 Navigation plays an essential role for many animals leading a mobile mode of life, and for central place foragers in particular. One important prerequisite for navigation is the ability to estimate distances covered during locomotion.

Fast simulation of large-scale growth models [PDF]
, 2010 We give an algorithm that computes the final state of certain growth models without computing all intermediate states. Our technique is based on a "least action principle" which characterizes the odometer function of the growth process.

Wold decomposition on odometer semigroups [PDF]
Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 2021 We establish a Wold-type decomposition for isometric and isometric Nica-covariant representations of the odometer semigroup. These generalize the Wold-type decomposition for commuting pairs of isometries due to Popovici and for pairs of doubly commuting isometries due to Słociński.
