A For loop specifies a counter variable of a type that does not define the >= or <= operator with parameters of its own type.The counter variable must be of a type that supports greater-than-or-equal (>=) and less-than-or-equal (<=) operators that compare their containing type....
There exists a Banach space which has the ap (even has a basis) but whose dual does not have the ap. W. B. Johnson [1] gave a simple construction of such a space. Let (Bn) be a sequence of finite-dimensional Banach spaces such that, for every ε > 0 and for every finite-...
