specific-question I'd guess linear-algebra - which was chosen by the OP - is not a good tag for H-infinity methods in control theory and Hardy space.. I have added hardy-spaces. But since the question is quite far from the stuff I know at least something about, I am not really confident in how to choose the tags there. (Although the title suggests control-theory might be a fitting tag...?)

Sorry this is very simple but I do not know. Why the H-infinity methods that are used in control theory are said to work on Hardy space? If the question is not appropriate then how H-infinity methods are related to Hardy space? May I request few comments? Sorry if the question is not clear:It ref...

$x,y,z >0$, prove $$\frac{x^4}{8x^3+5y^3}+\frac{y^4}{8y^3+5z^3}+\frac{z^4}{8z^3+5x^3} \geqslant \frac{x+y+z}{13}$$ Note: Often Stack Exchange asked to show some work before answering the question. This inequality was used as a proposal problem for National TST of an Asian country a few yea...

@MartinSleziak there are autoflag for many edits and also for rollback wars but there is no harm in raising a custom flag too, especially as the former might not be triggered for some reason.
