Universality and Non-Perturbative Definitions of 2D Quantum Gravity from Matrix Models
The universality of the non-perturbative definition of Hermitian one-matrix
models following the quantum, stochastic, or -like stabilization is
discussed in comparison with other procedures. We also present another
alternative definition, which illustrates the need of new physical input for
matrix models to make contact with 2D quantum gravity at the
non-perturbative level.Comment: 20 page
On the connections between Skyrme and Yang Mills theories
Skyrme theories on S^3 and S^2, are analyzed using the generalized zero
curvature in any dimensions. In the first case, new symmetries and integrable
sectors, including the B =1 skyrmions, are unraveled. In S^2 the relation to
QCD suggested by Faddeev is discussedComment: Talk at the Workshop on integrable theories, solitons and duality.

Generalized Integrability and the connections between Skyrme-Faddeev and Yang Mills theories
Skyrme theory on S^2 (Faddeev coset proposal), is analyzed with a
generalization of 0-curvature integrability, based on gauge techniques. New
expressions valid for models in the sphere are given. The relation of the
minimum energy configurations to gauge vacua is clarified. Consequences of
adding a potential term to break the SO(3) symmetry are discussed.Comment: Minor clarifications and corrections in the reference
