Center node: "products of effective topological spaces and a uniformly computable tychonoff theorem"
  Abstract: This article is a fundamental study in computable analysis. In the framework#N#of Type-2 effectivity, TTE, we investigate computability aspects on finite and#N#infinite products of effective topological spaces. For obtaining uniform#N#results we introduce natural multi-representations of the class of all#N#effective topological spaces, of their points, of their subsets and of their#N#compact subsets. We show that the binary, finite and countable product#N#operations on effective topological spaces are computable. For spaces with#N#non-empty base sets the factors can be retrieved from the products. We study#N#computability of the product operations on points, on arbitrary subsets and on#N#compact subsets. For the case of compact sets the results are uniformly#N#computable versions of Tychonoff's Theorem (stating that every Cartesian#N#product of compact spaces is compact) for both, the cover multi-representation#N#and the "minimal cover" multi-representation.
