  • Anticipation via canards in excitable systems 

    Köksal Ersöz E.; Desroches M.; Mirasso C.; Rodrigues S. (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 ...
  • Pro-C congruence properties for groups of rooted tree automorphisms 

    Garrido A.; Uria-Albizuri J. (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-$\mathcal{C}$ ...
  • Multi-GGS groups have the congruence subgroup property 

    Garrido A.; Uria-Albizuri J. (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 ...
