On deformation of Poisson manifolds of hydrodynamic type
2001
We study a class of deformations of infinite-dimensional Poisson manifolds of hydrodynamic type which are of interest in the theory of Frobenius manifolds. We prove two results. First, we show that the second cohomology group of these manifolds, in the Poisson-Lichnerowicz cohomology, is ``essentially'' trivial. Then, we prove a conjecture of B. Dubrovin about the triviality of homogeneous formal deformations of the above manifolds.
Integrable systems, Frobenius manifolds and cohomological field theories
2022
In this dissertation, we study the underlying geometry of integrable systems, in particular tausymmetric bi-Hamiltonian hierarchies of evolutionary PDEs and differential-difference equations.First, we explore the close connection between the realms of integrable systems and algebraic geometry by giving a new proof of the Witten conjecture, which constructs the string taufunction of the Korteweg-de Vries hierarchy via intersection theory of the moduli spaces of stable curves with marked points. This novel proof is based on the geometry of double ramification cycles, tautological classes whose behavior under pullbacks of the forgetful and gluing maps facilitate the computation of intersection…
Symmetric (79, 27, 9)-designs Admitting a Faithful Action of a Frobenius Group of Order 39
1997
AbstractIn this paper we present the classification of symmetric designs with parameters (79, 27, 9) on which a non-abelian group of order 39 acts faithfully. In particular, we show that such a group acts semi-standardly with 7 orbits. Using the method of tactical decompositions, we are able to construct exactly 1320 non-isomorphic designs. The orders of the full automorphism groups of these designs all divide 8 · 3 · 13.
El valor de un euro: la transacción banco de valencia
2015
El proceso competitivo para la venta del Banco de Valencia gestionado por el FROB duró 10 días. La venta de un banco de menos de 20.000 millones de euros de activo se adjudicó por un euro después de que recibiera 5.500 millones de euros de fondos públicos. Sin embargo, Oliver Wyman estimaba unas necesidades de 1.846 millones. Este trabajo analiza el valor del Banco de Valencia apoyándose en las cuentas anuales del Banco de Valencia de 2012 y de CaixaBank de 2013. Los resultados indican que el valor mínimo del Banco de Valencia para CaixaBank era de más de 4.000 millones de euros.
