Transverse Killing and twistor spinors associated to the basic Dirac operators
Adrian Mihai Ionescu, Vladimir Slesar, Mihai Visinescu +1
We study the interplay between basic Dirac operator and transverse Killing and twistor spinors. In order to obtain results for general Riemannian foliations with bundle-like metric…
