Smooth Complete Intersections with Positive-Definite Intersection Form
We classify the smooth complete intersections with positive-definite intersection form on their middle cohomology. There are two families. The first family are quadric hypersurfaces in P(4k+1) with k a positive integer. ...
Sheaves of Phi-Principal Parts
This thesis studies sheaves of phi-principal parts, a modification of the well-known sequence of sheaves of principal parts. In Chapter 1, we construct the sheaves of phi-principal-parts, and undertake their general study. ...
