Title:Cone avoidance and randomness preservation, part 2
Seminar:Logic Seminar
Speaker:Stephen G. Simpson, Pennsylvania State University
Abstract:
Let P be a nonempty, effectively closed set in Euclidean space. The Cone Avoidance Basis Theorem says that for any noncomputable point x, P contains a point which does not compute x. The Randomness Preservation Basis Theorem says that for any Martin-L"of random point y, P contains a point which preserves the randomness of y. Is it possible to combine these two theorems into one theorem? We prove that the only obstacle to combining them is K-triviality. This is joint work with Frank Stephan.
