- Approaching Some Problems in Finite Geometry Through Algebraic Geometry,
1 MB. Presented at RICAM, Linz, Austria, 5 May 2006
- The LLL Algorithm for Lattices, 123 KB. Presented at Rocky Mountain
Algebraic Combinatorics Seminar
23 Feb 2001
- Transfer Matrix Method, 452 KB. Presented at UW Algebra/Combinatorics Seminar.
Includes the generating function for the p-rank of points versus k-spaces
of PG(n,q). This gives the same answer as Hamada's formula
but is much more computationally efficient.
- Embedding Finite Partial Linear Spaces in Finite
Projective Planes, 306 KB. Presented at regional
Algebraic Combinatorics Seminar
17 Sept 2004
- The 2-transitive Complex Hadamard Matrices,
100 KB
- p-Ranks of Nets, 370 KB.
Derives the p-rank of a 3-net in terms of the left-multiplication group of
the corresponding loop.
- Quasigroup Cohomology and p-Ranks
of Nets, 394 KB.
More details from preceding talk, including proofs and cohomological interpretation
- Planes, Nets and Webs, 69 KB
- Knots. Presented to AMC contestants, Laramie in Spring 2006
- Two-graphs and skew two-graphs, 505 KB. Presented on Fri Nov 18, 1994
at the Rocky Mountain Algebraic Combinatorics Seminar at CSU
- Ovoids over Z/mZ, 543 KB. Presented on Fri Sept 26, 2008
at the Rocky Mountain Algebraic Combinatorics Seminar at CSU
