Line problems in nonlinear computational geometry
Frank Sottile, Thorsten Theobald
We first review some topics in the classical computational geometry of lines, in particular the O(n^{3+ε}) bounds for the combinatorial complexity of the set of lines in R^3 intera…

The Horn recursion for Schur P- and Q- functions: Extended Abstract
Kevin Purbhoo, Frank Sottile
A consequence of work of Klyachko and of Knutson-Tao is the Horn recursion to determine when a Littlewood-Richardson coefficient is non-zero. Briefly, a Littlewood-Richardson coeff…
