18.217 Graph Theory and Additive Combinatorics (Fall 2019, MIT OCW): Lecture 09 - Szemeredi's Graph Regularity Lemma IV: Induced Removal Lemma

18.217 Graph Theory and Additive Combinatorics

18.217 Graph Theory and Additive Combinatorics (Fall 2019, MIT OCW). Instructor: Professor Yufei Zhao. This course examines classical and modern developments in graph theory and additive combinatorics, with a focus on topics and themes that connect the two subjects. The course also introduces students to current research topics and open problems. (from ocw.mit.edu)

Lecture 09 - Szemeredi's Graph Regularity Lemma IV: Induced Removal Lemma

Professor Zhao explains a strengthening of the graph regularity method that is then used to prove the induced graph removal lemma. He also discusses applications of the regularity method in computer science to graph property testing.
