On the space of null geodesics of a spacetime: the compact case, Engel geometry and retrievability
Adrià Marín-Salvador, Roberto Rubio
We compute the contact manifold of null geodesics of the family of spacetimes $\{(\mathbb{S}^2\times\mathbb{S}^1, g_\circ-\frac{d^2}{c^2}dt^2)\}_{d,c\in\mathbb{N}^+\text{ coprime}}…
Correction to: Representation Growth and Rational Singularities of the Moduli Space of Local Systems
Avraham Aizenbud, Nir Avni, Roberto Rubio
We explain and correct a mistake in Section 2.6 and Appendix C of the first and second author's paper "Representation Growth and Rational Singularities of the Moduli Space of Local…
Complex Dirac structures: invariants and local structure
Dan Aguero, Roberto Rubio
We study complex Dirac structures, that is, Dirac structures in the complexified generalized tangent bundle. These include presymplectic foliations, transverse holomorphic structur…
Gauge theory for string algebroids
Mario Garcia-Fernandez, Roberto Rubio, Carl Tipler
We introduce a moment map picture for holomorphic string algebroids where the Hamiltonian gauge action is described by means of inner automorphisms of Courant algebroids. The zero…
On the Gelfand property for complex symmetric pairs
Roberto Rubio
We first prove, for pairs consisting of a simply connected complex reductive group together with a connected subgroup, the equivalence between two different notions of Gelfand pair…
Holomorphic string algebroids
Mario Garcia-Fernandez, Roberto Rubio, Carl Tipler
We introduce the category of holomorphic string algebroids, whose objects are Courant extensions of Atiyah Lie algebroids of holomorphic principal bundles, as considered by Bressle…
