• #### Anticipation via canards in excitable systems ﻿

(Chaos: An Interdisciplinary Journal of Nonlinear Science, 2019-01-14)
Neurons can anticipate incoming signals by exploiting a physiological mechanism that is not well understood. This article offers a novel explanation on how a receiver neuron can predict the sender’s dynamics in a ...
• #### Multi-GGS groups have the congruence subgroup property ﻿

(Proceedings of the Edinburgh Mathematical Society, 2018-11-08)
We generalize the result about the congruence subgroup property for GGS-groups to the family of multi-GGS-groups; that is, all multi-GGS-groups except the one defined by the constant vector have the congruence subgroup ...
• #### Pro-C congruence properties for groups of rooted tree automorphisms ﻿

(Archiv der Mathematik, 2018-11-21)
We propose a generalisation of the congruence subgroup problem for groups acting on rooted trees. Instead of only comparing the profinite completion to that given by level stabilizers, we also compare pro-$\mathcal{C}$ ...
