The Chifan-Ioana-Kunnawalkam Elayavalli Lifting Lemma
The construction of a separable II_1 factor without property Gamma, and which is not elementarily equivalent to the free group factors requires a lifting lemma, for which if four orthogonal projections in an ultraproduct of II_1 factors are chosen to satisfy certain properties, then sequence representatives of each projection can be chosen to also satisfy the same properties. We go over the proof of this lifting lemma.
