DESCRIPTION:Speaker: Floris van Doorn\nhosted by Matthew Kwan\nAbstract: Le
 an is a proof assistant which has a large mathematical library containing 
 results from most areas of mathematics. It contains a good foundation to 
 verify current research problems in various areas of mathematics\, and en
 ables new collaborative projects.In this talk I will give an overview of L
 ean and its mathematical library Mathlib\, and describe some of the exciti
 ng formalization projects in this area. In particular\, I will describe a
  recently finished project formalizing a generalization of Carleson's 196
 6 theorem in harmonic analysis\, about the pointwise convergence of Fourie
 r series. This is a major result in harmonic analysis with a difficult pr
 oof\, and this result has been fully verified in Lean. The formalization 
 was a large collaborative project with 17 main contributors.
