Apr 12, 2020 at 15:59 | comment | added | Arkadij | Thank you for the edit Sasha. Could you please add some argument explaining why $K$ is locally free? I am struggling to see why that is true. | |

Apr 12, 2020 at 12:36 | comment | added | Arkadij | I have changed the question to be more explicit now. It is important to me that it goes the way that I have mentioned, otherwise it is trivial as your answer shows. | |
Apr 12, 2020 at 12:33 | comment | added | Sasha | For me a resolution is a quasiisomorphism, no matter which direction it goes. | |
Apr 12, 2020 at 11:46 | comment | added | Arkadij | For me a resolutions is a complex of vector bundle $L^\bullet$ with a map $L^\bullet \to \mathcal{E}^\bullet$ which is a quasi-isomorphism. The map goes the wrong way in your case. | |
