The holonomy group of a locally symmetric space
Antonio J. Di Scala
We show that the holonomy group of a connected Riemannian locally symmetric space (not necessarily complete) without local flat factor is compact and has finite index in its normal…
Kähler-Einstein toric submanifolds of the projective space
Antonio J. Di Scala, Martín Sombra
We show that the Kähler-Einstein metrics on the four families of examples of symmetric toric Fano manifolds presented by Batyrev and Selivanova cannot be realized as metrics induce…
A note on the determinant 308 in Proskuryakov's linear algebra book
Antonio J. Di Scala, Martin Sombra
We put in evidence and correct a mistake in the formula for the determinant 308 in Proskuryakov's linear algebra book. We apply this formula to reprove the well-known fact that the…
On the condition number of the Vandermonde matrix of the nth cyclotomic polynomial
Antonio J. Di Scala, Carlo Sanna, Edoardo Signorini
Recently, Blanco-Chacón proved the equivalence between the Ring Learning With Errors and Polynomial Learning With Errors problems for some families of cyclotomic number fields by g…
Cones and Cartan geometry
Antonio J. Di Scala, Carlos E. Olmos, Francisco Vittone
We show that the extended principal bundle of a Cartan geometry of type , endowed with its extended connection , is isomorphic to the pri…
Homogeneous Riemannian manifolds with non-trivial nullity
Antonio J. Di Scala, Carlos E. Olmos, Francisco Vittone
We develop a general theory for irreducible homogeneous spaces , in relation to the nullity of their curvature tensor. We construct natural invariant (different and inc…
