Yes, it is, and that is my question. What if instead of ordered pairs it is sets. Is this concept well defined? I mean no one can use cartesian product anymore to represent this staff. What is the operation for this. On Feb 9, 2010, at 2:01 PM, saurabh gupta wrote: http://en.wikipedia.org

Not indeed. Cartesian product produces tuples as the result, but I am interested in the set form of these tuples. if there are two sets like X={A,B,C} & Y={A,B} then The Cartesian product will be: X.Y={(A,A),(A,B),(B,A),(B,B),(C,A),(C,B)} Whereas if insted of tuples sets were produced it w

The unordered pair will be a subset of cartesian product. What is the significance of it? On 8 February 2010 21:18, pinco1984 wrote: > Hi all, > > I have came across a problem and I am not aware if there is such a > thing in set theory and if so what is it called. > > Mainly I have several sets

Hi all, I have came across a problem and I am not aware if there is such a thing in set theory and if so what is it called. Mainly I have several sets that I am interested in their cartesian product. But this cartesian product should not be a set of ordered pairs but a set of sets. Basically unor
