Equivariant Compactifications of Two-Dimensional Algebraic Groups

  • Ulrich Derenthal (a1) and Daniel Loughran (a1)
Abstract

We classify generically transitive actions of semi-direct products on ℙ2. Motivated by the program to study the distribution of rational points on del Pezzo surfaces (Manin's conjecture), we determine all (possibly singular) del Pezzo surfaces that are equivariant compactifications of homogeneous spaces for semi-direct products .
