Abstract:
We study the structure of the Thom polynomials for A4(−)
singularities. We analyze the Schur function expansions of these polynomials.
We show that partitions indexing the Schur function expansions of Thom
polynomials for A4(−) singularities have at most four parts. We simplify the
system of equations that determines these polynomials and give a recursive
description of Thom polynomials for A4(−) singularities. We also give Thom
polynomials for A4(3) and A4(4) singularities.
