Hertling, Claus (ed.) et al., Frobenius manifolds. Quantum cohomology and singularities. Proceedings of the workshop, Bonn, Germany, July 8–19, 2002. Wiesbaden: Vieweg (ISBN 3-528-03206-5/hbk ). Aspects of Mathematics E 36, 91-112 (2004).
The author presents the concept of Frobenius structures in terms of linear symplectic geometry and exposes the role of the twisted loop group $$\mathcal{L}^{(2)} \text{GL}_N$$ of hidden symmetries in this theory.
