Structured　frames　in　L-2(R),　such　as　wavelet　and　Gabor　frames,　have　been　extensively　studied.　But　the　analysis　on　L-2(R+)　with　R+　=　(0,　infinity)　has　been　rarely　reported.　It　is　because　R　is　a　group　under　addition　but　R+　is　not.　This　results　in　L-2(R+)　admitting　no　traditional　wavelet　or　Gabor　frames.　Recently,　the　concept　of　F-a-frame　in　L-2(R+)　was　introduced　and　studied.　In　this　paper,　we　present　some　identities　and　inequalities　for　F-a-frame　sequences　in　L-2(R+).
