## André Nies: Topological isomorphism for classes of closed subgroups of the group of permutations of N

Tuesday, November 20, 2018, 10:30 Seminar room N0.003, Mathematical Institute, University of Bonn Speaker: André Nies (Auckland) Title: Topological isomorphism for classes of closed subgroups of the group of permutations of N Abstract: The closed subgroups of the group of permutations of $\mathbb{N}$ coincide with the automorphism groups of structures with domain $\mathbb{N}$. continue reading…

## André Nies: Structure within the class of K-trivial sets

SEMINAR ANNOUNCEMENT Title: Structure within the class of K-trivial sets Prof. André Nies Department of Computer Science University of Auckland Date:    6 February 2017 (Monday) Time:      4.00pm – 5.00pm Venue:     MAS Executive Classroom 1 #03-06, School of Physical and Mathematical Sciences  and quantum settings The K-trivial sets are antirandom in the sense that the initial segment complexity in terms of prefix-free Kolmogorov complexity K grows as slowly as possible. continue reading…
