Width is not Additive

Coauthors: Maggy Tomova

In 1954, Schubert showed that bridge number of knots is additive with respect to connected sum. Gabai defined the related notion of width of a knot and used it in his proof of property R. We will present results that show width is not additive with respect to connected sum. This is joint work with Maggy Tomova.
