MPIM Topology Seminar We cast the multivariable link signature as a signature defect, and explain how
it gives rise to genus bounds for link cobordisms. Then we discuss invariance
of the multivariable signature under 0.5-solvable cobordisms.
This is joint work with Anthony Conway, and Enrico Toffoli.
