Singular symplectic surfaces

Alice Garbagnati, Matteo Penegini, Arvid Perego

In this paper we classify all singular irreducible symplectic surfaces, i.e., compact, connected complex surfaces with canonical singularities that have a holomorphic symplectic fo…

Automorphisms of a family of surfaces with $p_{g} = q = 2$ and $K^{2} = 7$

Matteo Penegini, Roberto Pignatelli

We compute the automorphism group of all the elements of a family of surfaces of general type with $p_{g} = q = 2$ and $K^{2} = 7$ , originally constructed by C. Rito. We discuss the conseque…
