Subject: [harmonic] The dense subspace of H^p

To: harmonicanalysis@yahoogroups.com

Date: Tuesday, August 28, 2012, 10:05 PMHi everyone. I know this problem may be too trivial to you but I was confused by it for a long time. We know there is a result which claims that the intersection of H^p and L^1 is a dense subspace of H^p. However I don't know how to prove it (Stein's book mentioned it but didn't give a detailed proof) or which paper I can read.

Thank you!
