| Abstract: | We prove that a jointly conservative family of geometric functors between rigidly-compactly generated tensor triangulated categories induces a surjective map on Balmer spectra. From this we deduce a fiberwise criterion forBalmer's comparisonmap to be a continuous bijection. This gives short alternative proofs of the Hopkins-Neeman theorem and its generalization, due to Lau, to the case of a finite group acting trivially on an affine scheme. |
