报告内容简介：

　　We construct a van Est map from the Bott-Shulman double complex of a strict Lie 2-group to the Weil algebra of its associated strict Lie 2-algebra and prove that under appropriate connectedness assumptions, this map induces isomorphisms in cohomology. If time permits, as an application, we differentiate the Segal 2-form on the loop group.
