The differential geometry of the orbit space of extended affine Jacobi group A

Differential Geometry of Orbit space of Extended Affine Jacobi Group $A_n$

“…In the present paper I introduce a new class of groups that can be realized as monodromy groups of Dubrovin-Frobenius manifolds. This groups are higher dimension analogue of the group introduced in [1] and is denoted by J ( Ãn ). In the part I, we will given a notion of invariant ring for this group.…”
