Involution generators of mapping class groups

Abstract: The mapping class group of a surface plays an important role in low dimensional topology. Its various generating sets are known. Since it is not a quotient of a dihedral group, it cannot be generated by two involutions. A generating set consisting of 4-5 involutions has been known for more than 15 years. In this talk I will show how it is generated by 3 involutions.
