A family of arrangements for which the complement is homotopy equivalent to a wedge of spheres is described. One consequence is an application in commutative algebra: certain local rings are proved to be Golod, that is, all Massey products in their homology vanish.42 pagesAlgebraic TopologyCommutative AlgebraCombinatorics13F55, 55P15text
