Research Abstract 
(1) In [K], I gave a necessarily and sufficient condition for a Noetherian ring to have an arithmetic CohenMacaulayfication. I refine its construction by introducing a new notion, called pstandard sequences. (2) In [K], computed the depth of the canonical module. I compute local cohomology modules of the canonical module. (3) In 1978, Faltings prove the annihilator theorem. In 1982, he conjectured that the annihilator theorem holds under weaker assumption. I give an affirmative answer to his conjecture. (4) In 1991, Hukene [H] proved the uniform ArtinRees theorem and the uniform BrianconSkoda theorem. He also conjectured that these theorem hold under weaker assumption. I give an affirmative answer to [H, Conjecture 2.13] concerning these theorems. [F1] G.Faltings, Ueber die Annulatoren lokaler Kohomologiegruppen, Arch.Math. (Basel) 30 (1978), 473476.
