Friday, May 30, 2014, 16.30 Seminar room 1.007, Mathematical Institute, University of Bonn Speaker: Vassilis Gregoriades (Darmstadt) Title: A recursive theoretic view to the decomposability conjecture Abstract: The decomposability conjecture states that every function from an analytic space to a separable metric space, for which the preimage of a Σ^0_{m+1} set is a Σ^0_{n+1} set, where m=1,2,…n, is decomposable into countably many Σ^0_{n-m+1}-measurable functions on Π^0_n domains. continue reading…
