On the infinitesimal theory of Chow groups
The Chow groups of codimension-p algebraic cycles modulo rational equivalence on a smooth algebraic variety X have steadfastly resisted the efforts of algebraic geometers to fathom their structure. Except for the case p=1, which yields an algebraic group, the Chow groups remain mysterious. This …

Ample subschemes and partially positive line bundles
A common theme in algebraic geometry is that geometric properties of an algebraic variety are reflected in the subvarieties that are 'positively embedded' in it. Here the case of subvarieties of codimension one is classical and also fundamental to algebraic geometry: divisors correspond to line …
