Unirationality of hypersurfaces via highly tangent lines
Raymond Cheng
This article describes a unirationality construction for general low degree complete intersections in projective space which is based on a variety of highly tangent lines. Applied…

Profiles, linear spaces, and unirationality of complete intersections
Raymond Cheng
Complete intersections may be unexpectedly simple over fields of positive characteristic: for instance, they may be unirational despite being of general type. One explanation is gi…
