Torsionful Killing-Yano Forms under T-Duality: Transformation Conditions and Emergent Isometries
Özgür Kelekçi, Ümit Ertem, Özgür 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…
Generalized symmetry superalgebras
Özgür Açık, Ümit Ertem
We generalize the symmetry superalgebras of isometries and geometric Killing spinors on a manifold to include all the hidden symmetries of the manifold generated by Killing spinors…
Harmonic spinors from twistors and potential forms
Ümit Ertem
Symmetry operators of twistor spinors and harmonic spinors can be constructed from conformal Killing-Yano forms. Transformation operators relating twistors to harmonic spinors are…
Rigidity of Killing-Yano and conformal Killing-Yano superalgebras
Ümit Ertem
Symmetry algebras of Killing vector fields and conformal Killing vectors fields can be extended to Killing-Yano and conformal Killing-Yano superalgebras in constant curvature manif…
