Title: " On the shadowableness of singular flows. "
Abstract: The shadowing property is a landmark of the dynamical systems theory which is deeply
related to stability phenomena. Hyperbolicity is a famous source of systems with the shadowing property.
Nevertheless, the shadowing property does not hold for systems beyond the hyperbolic ones.
Indeed, the Lorenz attractor is a paradigmatic example of non-hyperbolic flow which reassembles
several properties of the hyperbolic ones, although it does not satisfy the shadowing property, as it was showed by M. Komuro.
Several years later L. Wen and X. Wen extended Komuro's results and proved that a sectional hyperbolic set does
not satisfy the shadowing property, unless it is hyperbolic. In this talk, we will push further this discussion
and ask whether the non-shadowableness of singular flows is due to the sectional hyperbolicity or it is, in fact,
a consequence of existence of attached singulaties.
This is a joint work with A. Arbieto, A Lopez and Y. Sanchez.

Title: "Quantum affine algebras: comparing two coproducts "
Abstract: GThe quantum affine algebras Uq are Hopf algebras with the coproduct D defined by Drinfeld and Jimbo; but they have also a “coproduct” Dv with values in a completion of Uq☼Uq , introduced by Drinfeld for quantum affinizations. While the relation between D and the action of the braid group (and also of the weight lattice, which is a subgroup of the braid group) is complicated and involves the R-matrix, Dv is by construction equivariant with respect to the action of the weight lattice. In this talk I will show that Dv can be obtained as “equivariant limit” of D.

Title: " On the Picard group of the stack of G-bundles on families of curves "
Abstract: Given a family of smooth projective curves and an arbitrary connected linear algebraic group G, we investigate the Picard group of the stack of relative G-bundles on the family.
This is a joint work with Roberto Fringuelli.
