Twistor operators on conformally flat spaces

summary:Summary: We describe explicitly the kernels of higher spin twistor operators on standard even dimensional Euclidean space $\mathcal{R}^{2l}$, standard even dimensional sphere $S^{2l}$, and standard even dimensional hyperbolic space $\mathcal{H}^{2l}$, using realizations of invariant differential operators inside spinor valued differential forms. The kernels are finite dimensional vector spaces (of the same cardinality) generated by spinor valued polynomials on $\mathcal{R}^{2l},S^{2l},\mathcal{H}^{2l}$
