,On the time and tape complexity of hyper(1)-AFL’s,ntained in the family of languages log(n)-tape reducible to the context-free languages. This implies that the family of block-indexed languages, together with the smallest hyper(1)-AFL, has a tractable membership question and tape complexity log.(n). Finally we note that the set {ww / wε {a, b}*} is not a block-indexed language.

Herausforderungen an das Gesundheitswesen, In the present paper, for any N and r, an infinite, decidable subdomain . [N,r] .. [N,r] is defined in a constructive way. The ensuing sufficient condition for the termination of a computation starting from N X. ... X. can be tested in a number of steps negligible with respect to those needed for reaching the n.f., if there is one.
