Title: A note on minimal finite quotients of mapping class groups
Authors: Bruno P. Zimmermann
Categories: math.GT Geometric Topology (math.GR Group Theory)
Comments: 8 pages
MSC: 57M99; 20F34
Abstract: We prove that the minimal nontrivial finite quotient group of the mapping
class group M_g of a closed orientable surface of genus g is the symplectic
group PSp(2g,Z_2), for g = 3 and 4 (this might remain true, however, for
arbitrary genus g > 2). We discuss also some results for arbitrary genus g.
