设A={a,b,c,d},R={,,,,},求R的自反、对称和传递闭包.
eflexive closure(R)={,,,,,}
Symmetric closure(R)={,,,,,,,}
i can't help you with your transitive closure !
LetW be a non-empty set and R a binary relation onW. Then R+,
the transitive closure of R, is the smallest transitive relation on W that contains R.
That is,
R+ =&{R`|R` is a transitive binary relation on W & (R included by R`)}:
Symmetric closure(R)={,,,,,,,}

C++编程题设A={a,b,c,d},A上的关系R={,,,}∪IA,判别关系R的性质,自反
A={a,b,c,d},定义一个关系式A,使其有自反,对称,传递
设 A={1,2,3,4,5},R∈A×A,R={,,},则R的自反闭包r(R)=____,对称闭包t(R)=____
集合A=(a,b,c)上的一个关系R,使R不具有五种性质(自反性,反自反性,对称性 反对称性,传递性)
设R是集合A={a,b,c,d}上的二元关系,R={,,,}求r(R),s(R),t(R)
闭包运算设集合A={a,b,c},在A上的关系是R={,,},求r(R),s(R),t(R)考虑的过程都最好写下
设集合A={a,b,c,d}上的关系R={,,,},求R•R-1
设集合A={a,b,c,d},A上的二元关系R={(a,b)(b,a)(b,c)(c,d)}求t(R)
设R是A上的自反关系,且当(a,b)属于R和(b,c)属于R时,必有(c,a)属于R,证明R是A上的等价关系
设R是A上的自反和传递关系,证明R∩R^-1是A上的等价关系.
设X={a,b,c}R4={(a,b),(b,c),(c,a)}求传递闭包t(R4)
