Automorphisms and quotients of quaternionic fake quadrics
A -ޑhomology quadric is a normal projective algebraic surface with the same Betti numbers as the smooth quadric in ސ 3 .A smooth -ޑhomology quadric is either rational or of general type with vanishing geometric genus.Smooth minimal -ޑhomology quadrics of general type are called fake quadrics.Here we study quaternionic fake …
