Compact supersymmetric solutions of the heterotic equations of motion in dimension 5
Marisa Fernandez, Stefan Ivanov, Luis Ugarte +1
We construct explicit compact supersymmetric solutions with non-zero field strength, non-flat instanton and constant dilaton to the heterotic string equations in dimension five. We…
Non-Kaehler Heterotic String Compactifications with non-zero fluxes and constant dilaton
Marisa Fernández, Stefan Ivanov, Luis Ugarte +1
We construct new explicit compact supersymmetric valid solutions with non-zero field strength, non-flat instanton and constant dilaton to the heterotic equations of motion in dimen…
Canonical connections on paracontact manifolds
Simeon Zamkovoy
The canonical paracontact connection is defined and it is shown that its torsion is the obstruction the paracontact manifold to be paraSasakian. A -homothetic transfor…
Curvature decomposition of G_2 manifolds
Richard Cleyton, Stefan Ivanov
Explicit formulas for the -components of the Riemannian curvature tensor on a manifold with a structure are given in terms of Ricci contractions. We define a conformally…
Warped product Kaehler manifolds and Bochner-Kaehler metrics
Georgi Ganchev, Vesselka Mihova
Using as an underlying manifold an alpha-Sasakian manifold we introduce warped product Kaehler manifolds. We prove that if the underlying manifold is an alpha-Sasakian space form,…
