四、關係閉包(closure of relation) 讓不滿足某一特定關係的集合,在經過增加最少序對的情況下,變得滿足該特定關係。 舉例來說,若在集合 S={1,2,3,4} 的笛卡爾積中有一集合 A={(1,1),(2,3)},則 A 不具備「自反性」,那麼要如何使 A 變得有「自反性」呢? 在A 集合中,我們少了 (2,2)、(3,3

By this functional relation for double Lerch series, we obtain explicit formulas for special values of alternating analogues of Tornheim's double series and double L-values.关键词: Functional relation Lerch type Tornheim double zeta function
一楼请不要答非所问 这个是个function，because according to the definition of a function each value of x can only have one corresponding vaule of y..在题目中每个x value只有一个y vaule ，所以这个是function determine
height and ethnicity are a more valid approach but it has some limitations in elderly population17,19. Some other methods of standardising spirometry indices including FEV1 divided by height squared and/or cubed have been found a better alternative to predict survival function and mortality in this...
