Existence and parametrization of structures over generically semisimple F-manifolds

Let (M,t0)(M,t^0) be an irreducible germ of a generically semisimple F-manifold. A generically semisimple F-manifold structure conjecture. The existence and parametrization assertions in parts (a) and (b) hold: (T)(T)-structures exist, and, when Tt0MT_{t^0}M is a Frobenius algebra, (TP)(TP)-structures exist; for a generically semisimple F-manifold with Euler field and sufficiently small representative MM, (TE)(TE)-structures exist, have the same Stokes structure at points of MKbifM-{\mathcal K}^{bif}, are uniquely parametrized by maps from the components of the analytic spectrum LML_M to C\mathbb C via the regular singular exponent invariant, and in the Frobenius-algebra case the structure with all regular singular exponents equal to m/2m/2 extends to a (TEP)(TEP)-structure of weight mm. These statements concern the existence and moduli of meromorphic connection structures associated with generically semisimple F-manifolds; the source presents them as a conjecture, but the supplied material gives no resolution evidence.
