| Nov 6, 2020 at 17:39 | comment | added | Martin Väth | This is exactly the situation which I have described (in case $\beta=0$ and equality of the norms): Unfortunately, exactly in this case it is not possible to conclude that the operator is closed, because $A\in B(X,Y)$ is an empty requirement then. | |
| Nov 6, 2020 at 8:54 | comment | added | Jarek Sarnowski | $X$ and $Y$ indeed have different norm. What if, additionally, norm on $X$ is equivalent to the norm $||(\beta I - A)y||_{Y}$? | |
