PCPs and Expander Graphs
A probabilistically checkable proof (PCP) is a special format for writing proofs that is very robust. In this format, a proof of a false theorem is guaranteed to have so many bugs that it can…

What kind of theorems are easy to state yet hard to prove? This question motivates the study of propositional proof complexity. In this introductory talk I will describe the three fundamental proof-complexity measures of proof…
