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 length, width, and space. These measures correspond to different aspects of the “hardness” of proving a given theorem. Then I will discuss the surprising relationships between these three measures and conclude with accessible and intriguing open questions in this area.
