Dao's question on the asymptotic behaviour of fullness

Commutative Algebra 2023-08-09 v1

Abstract

For a local ring (R,\M)(R, \M) of infinite residue field and positive depth, we address the question raised by H. Dao on how to control the asymptotic behaviour of the \M\M-full, full, and weakly \M\M-full properties of certain ideals (such notions were first investigated by D. Rees and J. Watanabe), by means of bounding appropriate numbers which express such behaviour. We establish upper bounds, and in certain cases even formulas for such invariants. The main tools used in our results are reduction numbers along with Ratliff-Rush closure of ideals, and also the Castelnuovo-Mumford regularity of the Rees algebra of \M\M.
