Isomorphism types of Rogers semilattices in the analytical hierarchy.

TL;DR: In this article, it was shown that any non-trivial Rogers semilattice of a non-zero natural numbers of a countable family cannot be isomorphic to a Rogers semiilattices of a π^1_m$-computable family.

NONBOUNDING n-C.E. Q-DEGREES

TL;DR: It is proved that for any noncomputable c.e. set A there is a non- computable c.

Dominance dimension: a common parametric formulation for integer-valued scientific impact indices

TL;DR: It is shown that by a suitable choice of parameters dominance dimension may specialize to the most widely known and used of those impact scores for the scientific output of authors which disallow endogenous reputation effects, including the Durfee- or h-number, the publication number and the citation number.

On the completeness of quantum computation models

TL;DR: The notion of computability is stable over infinite-dimensional vector spaces provided they have a finite "tensorial dimension" and permit to define an absolute notion of completeness for quantum computation models and give a precise meaning to the Church-Turing thesis.

On function languages and parallel computers

TL;DR: To widen their scope of applicability, functional languages need to include more features of nondeterminism and may need to be integrated with features from conventional languages, and the right sort of architectures for such extended languages may be less-specialised ones with a von Neumann flavour.
