The polynomial-time hierarchy [PDF]
The polynomial-time hierarchy is that subrecursive analog of the Kleene arithmetical hierarchy in which deterministic (nondeterministic) polynomial time plays the role of recursive (recursively enumerable) time.

On the Complexity of the Word Problem for Automaton Semigroups and Automaton Groups
In this paper, we study the word problem for automaton semigroups and automaton groups from a complexity point of view. As an intermediate concept between automaton semigroups and automaton groups, we introduce automaton-inverse semigroups, which are ...

State-by-state calculations for all channels of the exotic $(\mu^-,e^-)$ conversion process [PDF]
The coherent and incoherent channels of the neutrinoless muon to electron conversion in nuclei, $\mu^- (A,Z) \to e^- (A,Z)^*$, are studied throughout the periodic table.

Upper and lower bounds for first order expressibility [PDF]
We study first order expressibility as a measure of complexity. We introduce the new class Var&Sz[v(n),z(n)] of languages expressible by a uniform sequence of sentences with v(n) variables and size O[z(n)].

Linear Bounded Composition of Tree-Walking Tree Transducers: Linear Size Increase and Complexity [PDF]
Compositions of tree-walking tree transducers form a hierarchy with respect to the number of transducers in the composition. As main technical result it is proved that any such composition can be realized as a linear bounded composition, which means that

Translational lemmas, polynomial time, and (log n)j-space [PDF]
Translational lemmas are stated in a general framework and then applied to specific complexity classes. Necessary and sufficient conditions are given for every set accepted by a Turing acceptor which operates in linear or polynomial time to be accepted ...

The Gauss map of immersions of Riemannian manifolds in spaces of constant curvature
With an immersion x of a Riemannian n-manifold M into a Euclidean Nspace E there is associated the Gauss map, which assigns to a point p of M the n-plane through the origin of E and parallel to the tangent plane of x(M) at x(p), and is a map of M into ...

Mediated population protocols [PDF]
We extend here the Population Protocol (PP) model of Angluin et al. (2004, 2006) [2,4] in order to model more powerful networks of resource-limited agents that are possibly mobile.

Logspace self-reducibility [PDF]
A definition of self-reducibility is proposed to deal with logarithmic space complexity classes. A general property derived from the definition is used to prove known results comparing uniform and nonuniform complexity classes below polynomial time, and ...
