Symmetric Spaces of Exceptional Groups
Luis J. Boya
We adress the problem of the reasons for the existence of 12 symmetric spaces with the exceptional Lie groups. The 1+2 cases for and respectively are easily explained f…
Geometry of density sates
Luis J. Boya, Kuldeep Dixit
We reconsider the geometry of pure and mixed states in a finite quantum system. The rangesof eigenvalues of the density matrices delimit a regular simplex (Hypertetrahedron TN) in…
Supersymmetry and Polytopes
Luis J. Boya
We make an imaginative comparison between the Minimal Supersymmetric Standard Model and the 24-cell polytope in four dimensions, the Octacube.
Relation Between Holonomy Groups in Superstrings, M and F-theories
Adil Belhaj, Luis J. Boya, Antonio Segui
We consider manifolds with special holonomy groups SU(3), G2 and Spin(7) as suitable for compactification of superstrings, M-theory and F-theory (with only one time) respectively.…
