We discuss rigid compact complex manifolds of Kodaira dimension 1, arising as product–quotient varieties. First, we show that there is no free rigid action on the product of \((n-1)\) elliptic curves and a curve of genus at least 2. Then, we describe the occurring groups, study the quotients, and prove that there is always a suitable resolution of singularities preserving rigidity. Finally, we give a complete classification of the cases arising for minimal group orders.

摘要

We discuss rigid compact complex manifolds of Kodaira dimension 1, arising as product–quotient varieties. First, we show that there is no free rigid action on the product of \((n-1)\) elliptic curves and a curve of genus at least 2. Then, we describe the occurring groups, study the quotients, and prove that there is always a suitable resolution of singularities preserving rigidity. Finally, we give a complete classification of the cases arising for minimal group orders.
