Highly connected non-formal Milnor fibers via polyhedral products
Abstract
We show that the realization theorem of Fern\'andez de Bobadilla, which identifies the Milnor fiber of a weighted-homogeneous polynomial with the complement of a germ of analytic set, can be combined with the systematic Massey product constructions of Grbi\'c-Linton for moment-angle complexes to produce weighted-homogeneous polynomials whose Milnor fibers are arbitrarily highly connected and non-formal. The original application of this strategy, due to Fern\'andez de Bobadilla, used the Denham-Suciu classification of lowest-degree triple Massey products and yielded only -connected non-formal Milnor fibers. The Grbi\'c-Linton framework, which constructs non-trivial -fold Massey products in for arbitrary and in arbitrary cohomological degrees, removes this connectivity restriction entirely.
