In this paper , the author discusses the orthogonal transformation , pointing out that there is difference in essence between the two condition of equivalence 摘要對歐氏空間正交變換作了討論,指明了兩個等價條件的不同之處。
Owing to the strong condition of equivalence relation , there exist some limits , and it has been proved to be np - hard to find all reductions and a minimal reduction 由于等價關系條件較強,有一定的局限性,已經證明求所有約簡和最小約簡是np - hard問題。
This paper discusses the relationship between quasi - concave and pseudo - convex in the generalized convex function in the linear topological space and offers some conditions of equivalence 摘要討論了線性拓撲空間上廣義凸函數中的擬凸與偽凸之間的關系,并給出它們之間的一些等價條件。
