Let $X$ be a Banach Space , $Xsubseteq H,barX=H$,where $H$ is a Hilbert space $i:=Xto H$ defined by $i(x)=x$ and is continuous. Define $langle x,yrangle=langle ix,iyrangle$ then $langle X,X,(.,.) rangle$ to be a dual system.

Here I am trying to prove first Bilinear form. It's okay How to prove non-degenerate thing and dual system thing. Can someone explain this to me?



Thank you.
