The quaternionic Heisenberg group and Heterotic String Solutions with non-constant dilaton in dimensions 7 and 5
Marisa Fernandez, Stefan Ivanov, Luis Ugarte +1
New smooth solutions of the Strominger system with non vanishing flux, non-trivial instanton and non-constant dilaton based on the quaternionic Heisenberg group are constructed. We…
Quaternionic contact hypersurfaces in hyper-Kähler manifolds
Stefan Ivanov, Ivan Minchev, Dimiter Vassilev
We describe explicitly all quaternionic contact hypersurfaces (qc-hypersurfaces) in the flat quaternion space $\Hnn$ and the quaternion projective space. We show that up to a quate…
Non-Kaehler Heterotic String Solutions with non-zero fluxes and non-constant dilaton
Marisa Fernandez, Stefan Ivanov, Luis Ugarte +1
Conformally compact and complete smooth solutions to the Strominger system with non vanishing flux, non-trivial instanton and non-constant dilaton using the first Pontrjagin form o…
