Fyrirlesari: Tarmo Uustalu, Háskólinn í Reykjavík Titill: Skew categorical logic Staðsetning: Oddi O-106, 14. mars, 11:40. Ágrip: This is a talk on categorical logic as pioneered by Joachim Lambek in the late 1960s. We are interested in weak logics of a particular kind – logics defined by categories with some type of skew structure. I

22. febrúar, kl. 11:40, í Oddi O-106. Fyrirlesari: Sigurður Freyr Hafstein, Háskóli Íslands Titill: Contraction Metrics and their numerical computation, Part 2 Ágrip: Similar to Lyapunov functions, Contraction Metrics can be used to characterize the long term behavior of dynamical systems. We will discuss what they are, their relation to Lyapunov functions, and how they

8. february, kl. 11:40, í Oddi O-106 Fyrirlesari: Anders Claesson, Háskóli Íslands. Titill: Permutations with few inversions Ágrip: We consider permutations of [n] with at most n inversions; this is what we mean by permutation with few inversions. In particular, we present a curious generating function for permutations of [n] with exactly n inversion. Furthermore,
