Torsionful Killing-Yano Forms under T-Duality: Transformation Conditions and Emergent Isometries
Ãzgür Kelekçi, Ãmit Ertem, Ãzgür Açık
We investigate the transformation of Killing-Yano (KY) -forms under Abelian T-duality in the presence of a non-trivial three-form torsion. Using a torsionful, metric-compatible…

Algebra structure of conformal Killing-Yano forms in geometries with skew-symmetric torsion
Ãmit Ertem, Ãzgür Kelekçi, Ãzgür Açık
We consider conformal Killing-Yano forms corresponding to the antisymmetric generalizations of conformal Killing vectors to higher degree forms in the presence of skew-symmetric to…

Symmetries of modified Dirac operators in supergravity flux backgrounds
Ãmit Ertem
Modifications of Dirac operators in supergravity flux backgrounds are considered. Modified spin curvature operators and squares of modified Dirac operators corresponding to Schröd…
