Hi everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I am asking very basic question. But I think there is some important concept I am missing.

why is compactness important or why should one look out for compact sets?

I understand that they are bounded and closed and functions on them have good properties wrt to continuity and maxima or minima.

thanks
