内容摘要Abstract：Sparse optimization, aiming to find sparse solutions of linear inverse problems, is a popular research topic in applied mathematics and optimization, and nonconvex sparse optimization methods have been shown to enjoy efficient and robust sparsity promotion capability in vast applications. Gene regulatory networks is a fundamental tool in systems biology and biochemistry, while inferring gene regulatory networks from gene expression data at whole genome level is an arduous challenge.

In this talk, we will build up a bridge between sparse optimization and gene regulatory networks, and propose several nonconvex sparse optimization models for gene regulatory networks with different structures. Moreover, we will present the mathematical theory for nonconvex sparse optimization problems, including the consistency theory, the asymptotic theory and the stability theory of the model and the convergence theory of first-order iterative methods.
