在B-(p,r)不变凸函数的基础上,定义了一类新的广义凸函数:B-(p,r,a)不变凸函数,B-(p,r,a)不变拟凸函数,B-(p,r,a)不变伪凸函数,研究了涉及此类函数的分式规划,在更弱的条件下得到了几个对偶性条件.
Based on B-(p,r) Invex function,a class of B-(p,r,a) Invex function,B-(p,r,a) quasi-Invex function,B-(p,r,a) pseudo-Invex function have been defined,fractional programming involving this kind of functions has been researched,and many conditions of duality obtained under weaker convexity.
