Title: Categoricity in $L_{kappa, omega}$ when $kappa$ is strongly compact, Part 10

Abstract: In this series of talks, I will present a result of Makkai and Shelah that is an analogue to Morley's theorem in $L_{kappa, omega}$. This requires using $kappa$ being strongly compact, which says that any collection of sentences from $L_{kappa, kappa}$ is consistent if every $< kappa$ sized subset of it is consistent. The proof of this is much different than the proof of Morley's theorem and goes through a concept called 'forking,' which is an important extension of splitting.
