In this talk, we will focus on representations, cohomology,deformations, central extensions of Hom-Lie triple systems. Moreover, we study productstructure, complex structure, and complex product structure on involutivehom-Lie triple systems. This talk is areport on joint work with Ying Hou and Yao Ma.

A case-cohort design is proposed as a means of reducing cost inlarge cohort studies. In modeling process, case-cohort studies can acquire moreefficiency from taking parameter constraints into consideration. In this paper,we fit the Cox model with constraints to case-cohort data and develop aninverse probability weighted approach for regression analysis. We establishasymptotic properties by applying a Lagrangian approach based onKarush-Kuhn-Tucker conditions. We develop a constrainedminorization-maximization algorithm for the implementation of the proposedestimator. Simulation studies are conducted to assess the finite-sampleperformance. A data example from a Wilms tumor study is analyzed to demonstratethe application of the proposed method.

Higher structures appear moreand more in geometry, stimulated from the demands of going higher in theoreticphysics. In this talk, we would like to give an introduction to objects whichplay important roles in higher differential geometry, such as, gerbes, stacks,groupoids and give a hint to even higher versions of them, and hopefully withfun examples.
