Abstract

For Σ\Sigma an orientable surface of finite topological type having genus at least 3 (possibly closed or possibly with any number of punctures or boundary components), we show that the mapping class group Mod(Σ)Mod(\Sigma) has no faithful linear representation in any dimension over any field of positive characteristic.
