报告摘要:A Banach space is said to have the ball covering property if its unit sphere can be covered by countably many open balls off the origin. The ball covering property is a property that has close relationships with the topological properties and geometric properties of Banach spaces. In this talk, we will give a review of the historical literature and present some recent advances on this topic. Open problems will be proposed, and approaches will be discussed.
