ABSTRACT The known prepotential solutions F to the Witten-Dijkgraaf-Verlinde-Verlinde (WDVV) equation are parametrized by a set {alpha} of covectors. This set may be taken to be indecomposable, since F_{alpha oplus beta}=F_{alpha}+F_{beta}. We couple mutually orthogonal covector sets by adding so-called radial terms to the standard form of F. The resulting reducible covector set yields a new type of irreducible solution to the WDVV equation. Comment: 1+4 pages

##### Article: Modular Frobenius manifolds and their invariant flows
[hide abstract]
ABSTRACT: The space of Frobenius manifolds has a natural involutive symmetry on it: there exists a map \$I\$ which send a Frobenius manifold to another Frobenius manifold. Also, from a Frobenius manifold one may construct a so-called almost dual Frobenius manifold which satisfies almost all of the axioms of a Frobenius manifold. The action of \$I\$ on the almost dual manifolds is studied, and the action of \$I\$ on objects such as periods, twisted periods and flows is studied. A distinguished class of Frobenius manifolds sit at the fixed point of this involutive symmetry, and this is made manifest in certain modular properties of the various structures. In particular, up to a simple reciprocal transformation, for this class of modular Frobenius manifolds, the flows are invariant under the action of \$I\,.\$

• ##### Article: Many-particle mechanics with D (2, 1; α) superconformal symmetry
[hide abstract]
ABSTRACT: We overcome the barrier of constructing superconformal models in one space dimension for more than three particles. The D (2, 1; α) superalgebra of our systems is realized on the coordinates and momenta of the particles, their superpartners and one complex pair of harmonic variables. The models are determined by two prepotentials, F and U, which must obey the WDVV and a Killing-type equation plus homogeneity conditions. We investigate permutation-symmetric solutions, with and without translation invariance. Models based on deformed A n and BCD n root systems are constructed for any value of α, and exceptional F n -type and super root systems admit solutions as well. Translation-invariant mechanics occurs for any number of particles at (osp(4|2) invariance as a degenerate limit) and for four particles at arbitrary α (three series).
