... On the other hand, suppose that g: R → R is the function defined by g (x) = x4 – x for each real number x Let x1 = 0 and x2 =1.Then g(x1) = g(0) = (0)4 – 0 = 0 g(x2) = g(1) = (1)4 – (1) = 1 – 1 = 0 Hence g(x1) = g(x2) but x1 x2 (0 ≠ 1) – that is, g is not one to-one because there exist real number ...

... We briefly review the five standard systems of reverse mathematics. For completeness, we include systems stronger than arithmetical comprehension, but these will play no part in this paper. Details, general background, and results, as well as many examples of reversals, can be found in Simpson [1999 ...

... Let S be a set. A multiset M over S is a collection of objects from S that the elements of S can be repeated; the repeated objects are indistinguishable. For instance, the collection {a, a, b, c, c, c} is a multiset of 6 objects over the set {a, b, c}; of course it is also a multiset over the set {a ...
