摘要：
Given a finitely generated tensor norm a, we investigate weak* densities of adjoint operators in the Banach operator ideal A associated with a. We also study relations between the a-approximation properties and weak* densities of finite rank adjoint operators in A. Some examples are given satisfying that all adjoint operators are not weak* dense in the ideal of compact operators. (C) 2020 Elsevier Inc. All rights reserved.
