Abstract
The analysis of the critical points of a one-parameter family of polynomials allows us to define sets of pseudolines in the fundamental region of the affine Weyl group associated with the root lattice \(A_{2}\). The pseudolines are transformed into configurations of lines containing the prototiles of substitution tilings with n-fold symmetry. The configurations of lines have been used recently to obtain hypersurfaces with many singularities. Calabi–Yau threefolds can be constructed from resolutions of some of the singular hypersurfaces.
