报告题目：Separable universal Banach lattices
报告人： 南开大学数学学院，李磊
摘 要：I will talk about the construction of separable universal injective and projective lattices for the class of all separable Banach lattices. This is the joint work with Denny H. Leung, Timur Oikhberg and Mary A. Tursi.
报告题目：$L^2$-isometry on projection lattices
报告人：王利广（曲阜师范大学）
摘 要：Recently, Geh\'{e}r and \u{S}emrl have characterized the general form of surjective isometries of the set of all projections on an infinite-dimensional separable Hilbert space using unitaries and antiunitaries. In this talk, we will study the surjective $L^2$-isometries of the projection lattice of an infinite dimensional Hilbert space and show that every such isometry can also be described by unitaries and antiunitaries. This talk is based on joint work with Wenming Wu and Wei Yuan.
