Reduced Wu and generalized Simon invariants for spatial graphs
Published online by Cambridge University Press: 20 February 2014
Abstract
We introduce invariants of graphs embedded in S3 which are related to the Wu invariant and the Simon invariant. Then we use our invariants to prove that certain graphs are intrinsically chiral, and to obtain lower bounds for the minimal crossing number of particular embeddings of graphs in S3.
