A new metric for hyperbolic SU(2) 2-monopoles

• Thomas Galvin (University of Leeds)

Room: L50 (Psychology Auditorium) There is significant interest in the L^2 metric on the moduli space of SU(2) Euclidean monopoles, both because it is hyperkähler, and because it models monopole dynamics. No direct analogue of such a metric exists for hyperbolic monopoles, though alternatives have been suggested. I will discuss a new metric on the moduli space of parity inversion symmetric Hyperbolic SU(2) 2-monopoles based on the methods of O. Nash. This is joint work with my supervisor Derek Harland and Linden Disney-Hogg.

SL2-Tilings with Translational Symmetry

• Marie-Anne Bourgie (Université Laval)

Room: L50 (Psychology Auditorium) An SL2-tiling is a bi-infinite matrix in which all adjacent 2 × 2 minors are equal to 1. Positive integer SL2-tilings were introduced by Assem, Reutenauer and Smith as generalisations of classical Conway–Coxeter frieze patterns. We show that positive integer SL2-tilings with translational symmetry are in bijection with triangulations of annuli. We use this correspondence to study the properties of periodic positive integer SL2-tilings. This is joint work with Véronique Bazier-Matte, Anna Felikson, and Pavel Tumarkin.
