Abstract.Here we study existence or non-existence of certain linear monads (or the semistability of their cohomology sheaves) on certain projective varieties, mainly if $\mbox{\rm Num}(X) \cong \mathbb {Z}$. We use in an essential way the proofs in a paper by Fløystad and in a paper by Jardin and Miró-Roig: we just easily extend their proofs to our more general set-up.
