Equations of Parametric Surfaces with Base Points via Syzygies
William Adkins, J. William Hoffman, Hao Hao Wang
Let be a parametric surface in $\proj{3}$ given as the image of $ϕ: \proj{1} \times \proj{1} \to \proj{3}$. This paper will show that the use of syzygies in the form of a combi…

J. William Hoffman, Hao Hao Wang
We prove analogs of results of Cox/Schenck on the structure of certain ideals in the bigraded polynomial ring k[s,u;t,v].
