https://doi.org/10.1007/b138948in P. and P.. A word is called abelian 2-repetition free, or in short a-2-free, if it does not contain any abelian square as a subword. Let Σ be the four letter alphabet a,b,c,d. We give an example of a uniformly growing endo-morphism g:Σ.→Σ.; with ¦g(a)¦=85; such that the iteration of g yields an a

The family of languages generated by quasi-deterministic 0L systems is properly included by the family of 0L languages and properly includes that of D0L languages. A 0L system

Moreover, it provides a natural grammatical characterization of the context-free hypergraph languages of bounded degree. For grammars with the apex property it is

Wolfgang Greiner,Oliver Damm MPH, B. Sc.h sets reduce. We show even with respect to very flexible reductions that NP cannot have sparse hard sets unless P = NP; an immediate consequence of our results is: If any NP-complete set conjunctively reduces to a sparse set, then P = NP. We also show that any set . that reduces to some sparse set
