From exceptional groups to del Pezzo surfaces and simultaneous log resolutions via principal bundles over elliptic curves

I. Grojnowski, N. I. Shepherd-Barron

Published 2015-07-07Version 1

We show that simultaneous log resolutions of simply elliptic singularities can be constructed inside suitable stacks of principal bundles over elliptic curves. In particular, we give a direct geometrical construction of del Pezzo surfaces from the corresponding exceptional simple algebraic groups.
