一类带参数的二次规划解的结构及稳定性

Solution Structure and Stability for Pararnetric Qtiadratic Programs

研究一类参数二次规划问题。利用Ｌａｇｒａｎｇｅ函数把问题转化为一个鞍点问题，讨论了问题有解的必要与充分条件，指出解的结构，还得到在连续性意义下的稳定性结果。

class:of parametric quadratic program problems are dealed with. By Lagrange function theproblem is transformed into a saddle-point problem,then a neccesary and sufficient condition forthe existence of solution is given. The stability of the solution is also investigated.
