\u201cMinimal number of involution generators for the mapping class group\u201d<\/p>\n
Abstract: The mapping class group Mod(\u03a3g) of a closed oriented surface \u03a3g of genus g is the group of isotopy classes of orientation\u2013preserving diffeomorphisms \u03a3g \u2192 \u03a3g. It is a fundamental object in low-dimensional topology. It is known that this group can be generated by finitely Dehn twists, torsion elements and also by involutions. In this talk I will discuss how to generate the group Mod(\u03a3g) with the smallest number of generators consisting of these types of elements, particularly our recent result on involutions: Mod(\u03a3g) is generated by three involutions.<\/p>\n
