+//Abstract://
+A representation-free logic-base approach for computing with infinite objects will be presented. The logic is intuitionistic first-order logic extended by strictly positive inductive and coinductive definitions. Algorithms can be extracted from proofs via realizability. The approach allows to deal with objects like the real numbers and nonempty compact sets of such. More general, it allows to deal with compact metric spaces that come equipped with a finite set of contractions such that the union of their ranges covers the space, and with continuous maps between such spaces. The computational power of the approach is equivalent to that of type-two theory of effectivity.
