Nondifferentiable Multiobjective Programming under Generalized d_I-G-Type I Invexity

To relax convexity assumptions imposed on the functions in theorems on sufficient conditions and duality,new concepts of generalized dI-G-type Ⅰ invexity were introduced for nondifferentiable multiobjective programming problems.Based upon these generalized invexity,G-Fritz-John （G-F-J） and G-Karnsh-Kuhn-Tucker （G-K-K-T） types sufficient optimality conditions were established for a feasible solution to be an efficient solution.Moreover,weak and strict duality results were derived for a G-Mond-Weir type dual under various types of generalized dI-G-type Ⅰ invexity assumptions.

修辞构式中名词复现的条件及其语用功能

修辞构式中,名词的复现属于非常规性复现。前位名词与后位名词同形异质。名词之所以能够复现是因为构式和语境为其提供了外部条件,但根本原因是在于构式中提取使用了名词的属性义。名词复现可以突出表述重点,表达主观评价,也可以强化关联,补偿表义。修辞构式中的名词复现体现了名词的自足性。
