Quaternionic Kähler and hyperKähler manifolds with torsion and twistor spaces
Stefan Ivanov, Ivan Minchev
The target space of a (4,0) supersymmetric two-dimensional sigma model with Wess-Zumino term has a connection with totally skew-symmetric torsion and holonomy contained in Sp(n)Sp(…

Connection with torsion, parallel spinors and geometry of Spin(7) manifolds
Stefan Ivanov
We show that on every Spin(7) manifold there always exists a unique linear connection with totally skew-symmetric torsion preserving a nontrivial spinor and the Spin(7) structure.…

Almost contact manifolds, connections with torsion and parallel spinors
Thomas Friedrich, Stefan Ivanov
We classify locally homogeneous quasi-Sasakian manifolds in dimension five that admit a parallel spinor of algebraic type with respect to the unique connection $…
