Sally Cockburn, professor of mathematics, presented her paper, "Preimages of Small Geometric Cycles," at the Combinatorics and Optimization Seminar at the University of Ottawa on Jan. 29. This work is part of her ongoing research into measuring the complexity of straight-line representations of networks, in terms their vertex adjacency and edge crossing structures.
The paper will appear in the Journal of Combinatorial Mathematics and Combinatorial Computing.
