In this talk, we will introduce the quantile regression. The quantile regression model is a valuable alternative to the conditional mean models. While mean regression is confined to estimating the mean function of the response, quantile regression offers a systematic strategy for examining how covariates influence the location, scale, and shape of the entire response distribution. In addition, quantile regression does not assume any parametric form on the error distribution, and thus is able to accommodate non-normal errors. We also introduce some work on the variable selection in quantile varying coefficient models.

In this talk, I present some new results of nonnegative tensors. Irreducible tensors, primitive tensors, multistochastic tensors are discussed. Also the spectral radius of nonnegative tensors are studied.

学术报告Some Aspects of Finite Element Approximation for Reissner-Mindlin Plates石钟慈教授中国科学院院士、计算数学研究所研究员The Reissner-Mindlin plate model is one of the most commonly used models of a moderate-thick to thin elastic plate. However, a direct finite element approximation usually yields very poor results, which is referred to LOCKING phenomenon.In the past two decades, many effo...

In this talk, we will discuss some Siu-Sampson type results for pseudo-harmonic maps between pseudo-Hermitian manifolds. Under some kind of nonpositive curvature assumptions for the target manifolds, we derive pseudo- pluriharmonicity of the pseudo- harmonic maps. By further rank conditions, some pseudo- holomorphicity results of these pseudoharmonic maps are established.
