Generalized Killing spinors associated with the Ricci tensor
Natsuki Imada
In this paper, we introduce the notion of Ricci Killing spinors on Riemannian spin manifolds, which form a class between generalized Killing spinors and standard Killing spinors. W…

Higher spin Killing spinors on 3-dimensional manifolds
Yasushi Homma, Natsuki Imada, Soma Ohno
We define higher spin Killing spinors on Riemannian spin manifolds in arbitrary dimension and study them in detail in dimension three. We prove a rigidity result for 3-dimensional…
