Abstract

This paper studies the map between polyhedral products ZK(C\underlineX,\underlineX)\toZK(Σ\underlineX,*) induced from the pinch maps (CXi,Xi)→(ΣXi,*), which is the higher order Whitehead product if K is the boundary of a simplex. When K is a shifted complex, a wedge decomposition of ZK(C\underlineX,\underlineX) is given by the authors. Based on this decomposition, when K is shifted, the induced pinch map is explicitly described as a wedge of iterated Whitehead products each of which includes at most one higher product. As a corollary, the Jacobi identity of Whitehead products including higher products due to Hardie is generalized.
