@User:J947 Hi, why did you revert the delete request? This was a typo (or German). I created this article and then moved it to Kato's inequality. So you can delete it, no worry.--Tensorproduct (talk) 23:36, 11 July 2023 (UTC)
- @Tensorproduct: I believe it's a helpful redirect to have around. If you really want it deleted then you can put {{db-g7}} on it but there's really no need. J947 † edits 00:41, 12 July 2023 (UTC)
