Birational geometry of O'Grady's six dimensional example over the Donaldson-Uhlenbeck compactification
Yasunari Nagai
We determine the birational geometry of O'Grady's six dimensional example over the Donaldson-Uhlenbeck compactification, by looking at the locus of non-locally-free sheaves on the…

Non-locally-free locus of O'Grady's ten dimensional example
Yasunari Nagai
We give a completely explicit description of the fibers of the natural birational morphism from O'Grady's ten dimensional singular moduli space of sheaves on a K3 surface to the co…
