Koszul duality for monoids and the operad of enriched rooted trees
Miguel A. Mendez
We introduce here the notion of Koszul duality for monoids in the monoidal category of species with respect to the ordinary product. To each Koszul monoid we associate a class of K…
Yukawa Structure from U(1) Fluxes in F-theory Grand Unification
A. Font, L. E. Ibanez
In F-theory GUT constructions Yukawa couplings necessarily take place at the intersection of three matter curves. For generic geometric configurations this gives rise to problemati…
Shearing Expansion-free Spherical Anisotropic Fluid Evolution
L. Herrera, N. O. Santos, A. Wang
Spherically symmetric expansionfree distributions are systematically studied. The whole set of field equations and junction conditions are presented for a general distribution of d…
Algebras and non-geometric flux vacua
Anamaria Font, Adolfo Guarino, Jesus M. Moreno
In this work we classify the subalgebras satisfied by non-geometric Q-fluxes in type IIB orientifolds on T^6/(Z_2 x Z_2) with three moduli (S,T,U). We find that there are five suba…
The Dynamical Behaviour of Test Particles in a Quasi-Spherical Spacetime and the Physical Meaning of Superenergy
L. Herrera, J. Carot, N. Bolivar +1
We calculate the instantaneous proper radial acceleration of test particles (as measured by a locally defined Lorentzian observer) in a Weyl spacetime, close to the horizon. As exp…
Disks around Brown Dwarfs in the Sigma Orionis Cluster
K. L. Luhman, J. Hernandez, J. J. Downes +2
We have performed a census of disks around brown dwarfs in the Sigma Ori cluster using all available images from IRAC onboard the Spitzer Space Telescope. To search for new low-mas…
