Set-theoretic generation of ideals
On Two Conjectures About Polynomial Rings.
Rational Double Points on a Rational Surface.
Some theorems on generation of ideals in affine algebras.
ACM bundles, quintic threefolds and counting problems
We review some facts about rank two arithmetically Cohen-Macaulay bundles on quintic threefolds. In particular, we separate them into seventeen natural classes, only fourteen of which can appear on a general quintic. We discuss some enumerative problems arising from these.
Smooth degeneration of complete intersection curves in positive characteristc.
