(TE)-structures over the irreducible 2-dimensional globally nilpotent F-manifold germ

We find formal and holomorphic normal forms for a class of meromorphic connections (the so-called $(TE)$-structures) over the irreducible $2$-dimensional globally nilpotent $F$-manifold germ ${\mathcal{N}}_2$. We find normal forms for Euler fields on ${\mathcal{N}}_2$ and we characterize the Euler fields on ${\mathcal{N}}_2$ which are induced by a $(TE)$-structure.
