Item Open Access Slopes of links and signature formulas(American Mathematical Society, 2021) Degtyarev, Alex I.; Florens, V.; Lecuona, A.G.; Vershik, A.M.; Buchstaber, V.M.; Malyutin, A.V.We present a new invariant, called slope, of a colored link in an integral homology sphere and use this invariant to complete the signature formula for the splice of two links. We develop a number of ways of computing the slope and a few vanishing results. Besides, we discuss the concordance invariance of the slope and establish its close relation to the Conway polynomials, on the one hand, and to the Kojima-Yamasaki η-function (in the univariate case) and Cochran invariants, on the other hand. © 2021 by the American Mathematical Society.
