概要

• 論文の詳細を見る

• In this paper, we decide the heighest Lyubeznik number λ2.2 (A) by the number of the connected components of its punctured spectrum, where A is a complete noetherian local ring of dimension 2 containing a separably closed residue field, using the spectral sequence. This assertion gives a counterexample for Lyubeznik's question (cf. Question 4.5 of [L]).
