I didn't understand why there was an operator A : H -> H until I read the proof of Royden's book
I didnt understand anything of these. Just went off over my head!!
If we have the equation Au=f and i proved a priori estimate of this equation between two Hilbert spaces. can we say A be an isomorphism ?
