Polynomial clone reducibility (Q2436621)

In the paper under review, the author investigates randomness under polynomial clone reducibilities. The major result states that if \(x\) is Kurtz random and \(C_1\subseteq C_2\) are polynomial clones, then there is a \(y\) that is \(C_1\)-reducible to \(x\) but not \(C_2\).
