2016 seminar talk: A basis theorem for the complement of the first Baire class
Talk held by Ben Miller (KGRC) at the KGRC seminar on 2016-03-17.
Abstract
I will sketch a proof of the fact that there is a six-element basis, under topological embeddability, for the family of Borel functions which are not in the first Baire class. This is joint work with Raphaël Carroy.
