Good Basic Invariants for Elliptic Weyl Groups and Frobenius Structures
In this paper, we define a set of good basic invariants for the elliptic Weyl group for the elliptic root system. For an elliptic root system of codimension $1$, we show that a set of good basic invariants gives a set of flat invariants obtained by Saito and Taylor coefficients of the good basic inv...

| Zusammenfassung: | In this paper, we define a set of good basic invariants for the elliptic Weyl
group for the elliptic root system. For an elliptic root system of codimension
$1$, we show that a set of good basic invariants gives a set of flat invariants
obtained by Saito and Taylor coefficients of the good basic invariants give the
structure constants of the multiplication of the Frobenius structure obtained
by the author. |
