Computational limitations of Stochastic Turing machines and Arthur-Merlin games with small space bo games against nature, Arthur-Merlin games, or interactive proof systems with public coins. We give an overview on complexity classes defined by STMs with space resources between constant and logarithmic size and constant or sublinear bounds on the number of alternations. New lower space bounds are

Resolution proofs, exponential bounds, and Kolmogorov complexity,ion is a significant simplification in the proof and strengthening of the bound, as compared to [13]. We use on the one hand a simplification similar to the one suggested by Beame and Pitassi in [1] for the case of the pidgeon hole clauses. Additionally, we base our construction on a simpler version

Specifying computations using hyper transition systems,ic non-determinism as well as recursion. Hyper transition are a generalization of transition systems and are suited for the specification of computations by means of properties that atomic steps in a computation have to satisfy. As an application we use a hyper transition system to give an operation

A shift-invariant metric on ,, inducing a non-trivial topology,duced by this metric is perfect but not compact. Moreover we prove that the new space is “suitable” for the study of the dynamical behavior of CA. In this context sensitivity assumes a stronger meaning than before (usually .. is given the product topology). Now cellular automata are sensitive if the

It has been suggested that as many as 20% of all patients seeking medical treatment have neurologic problems, either as the presenting complaint or as an associated condition complicating the primary illness. Thus, it is fitting that Sp
