摘要
We show that instanton bundles of rank , defined as the cohomology of certain linear monads, on an -dimensional projective variety with cyclic Picard group are semistable in the sense of Mumford-Takemoto. Furthermore, we show that rank linear bundles with nonzero first Chern class over such varieties are stable. We also show that these bounds are sharp.
