Title: Ornstein Theory II: Stacks and Gadgets

Abstract: This talk will be a continuation of the talk given last week. During this talk, The geometric representation of p.m.p. actions given by the Rokhlin lemma will be developed even further, which will lead to the definitions of gadgets and their labeling properties.
