Research Interests for Chadmark L. Schoen
Research Interests: Algebraic Geometry
I work on the geometry and arithmetic of figures defined by polynomial equations.
I am especially interested in the geometry of algebraic curves, surfaces, threefolds and fourfolds over the complex numbers,
over numbers fields, over finite fields, over fields of transcendence degree one over finite fields and over discrete valuation rings with
perfect residue field. More specifically
I study elliptic surfaces, elliptic threefolds, CalabiYau
varieties, abelian varieties and surfaces of general type.
I am interested in Chow groups of algebraic varieties and
the relationship between a variety's Chow groups and its
arithmetic and geometric properties.  Keywords:
 Algebraic geometry
 Areas of Interest:
Geometry of algebraic varieties Algebraic Cycles Chow Groups
