报告摘要: (1) In this talk, we focus on the absolute value equation (AVE) and one of its extension, the absolute value equation associated with second order cone

  (SOCAVE). For each equation, we propose unified smoothing functions that

  can work along with smoothing-type algorithm. Some discovery based on

  numerical comparisons is very interesting which may suggest a good choice

  of smoothing function for the other contexts.


   (2) It iswell known that Euclidean Jordan algebra is a unified framework for symmetric cone programs, including positive semidefinite programs and second-order cone programs. Unlike symmetric cone programs, there is no unified analysis technique to deal with nonsymmetric cone programs. Nonetheless, there are several common concepts when dealing with generalconic optimization. More specifically, we believe that spectral decomposition associated with cones, nonsmooth analysis regarding cone-functions, projections onto cones, and cone-convexity are the bridges between symmetric cone programs and nonsymmetric cone programs. Hence, this talk is devoted to looking into the first three items in the setting of nonsymmetriccones. The importance of cone-convexity is recognized in the literature so that it is not discussed here. All results presented in this paper are very crucial to subsequent study about the optimization problems associated with nonsymmetric cones.
