Multivariable signatures, genus bounds and 0.5-solvable cobordisms

We refine prior bounds on how the multivariable signature and the nullity of a link change under link cobordisms. The formula generalizes a series of results about the 4-genus having their origins in the MurasugiTristram inequality, and at the same time extends previously known results about concord...
