Abstract

A differential geometric approach to Milnor-Massey higher order linking numbers for generic links is devised, via Chen's theory of iterated path integrals. Massey linking numbers arise from curvature forms of nilpotent "topological" connections, determined by the link structure, and interpreted in terms of intersection theory, leading to a fairly easy computation thereof. A version of the Turaev-Porter theorem expressing equality of Milnor and Massey linking numbers is also exhibited along the same lines, by computing suitable flat connection parallel transport operators in two different ways.
