When you extend the projective line RP1 to the complex half plane, with RP1 as the boundary at infinity, is RP1 the line at infinity for the half plane that we technically cannot "see"? I'm confused about how RP1 fits into the picture of the complex half plane when you make this extension.(adsbygoogle = window.adsbygoogle || []).push({});

Thanks!
