Composition algebras and the two faces of
Luis J. Boya, R. Campoamor-Stursberg
We consider composition and division algebras over the real numbers: We note two rôles for the group : as automorphism group of the octonions and as the isotropy group of a…
Holonomy Groups Coming From F-Theory Compactification
Adil Belhaj, Luis J. Boya, Antonio Segui
We study holonomy groups coming from F-theory compactifications. We focus mainly on SO(8) as 12-4=8 and subgroups SU(4), Spin(7), G2 and SU(3) suitable for descent from F-theory, M…
On F-theory Quiver Models and Kac-Moody Algebras
Rachid Ahl Laamara, Adil Belhaj, Luis J. Boya +2
We discuss quiver gauge models with bi-fundamental and fundamental matter obtained from F-theory compactified on ALE spaces over a four dimensional base space. We focus on the base…
Commutativity of missing label operators in terms of Berezin brackets
Luis J. Boya, R. Campoamor-Stursberg
We obtain a criterion on the commutativity of polynomials in the enveloping algebra of a Lie algebra in terms of an involution condition with respect to the Berezin bracket. As an…
On Local F-theory Geometries and Intersecting D7-branes
Rachid Ahl Laamara, Adil Belhaj, Luis J. Boya +1
We discuss local F-theory geometries and theirs gauge theory dualities in terms of intersecting D7-branes wrapped four-cycles in Type IIB superstring. The manifolds are built as el…
