Dominant functions and high sets

We prove Martin's theorem that \(A'\geq_T\emptyset''\) if and only if $A$ computes a function that bounds every total computable function almost everywhere. Then we will begin discussing the infinite injury priority tree construction of Sacks' theorem that there exists a high incomplete c.e. set.

Examples of Factors and Conditional expectation

We will discuss examples of factors of measure preserving systems arising from products and skew-products. We will also briefly define regular and separable extensions. We will then introduce the concept of Conditional expectation and prove some of its basic properties.
