Watson-Crick DOL systems: generative power and undecidable problems
Original language description
The properties of Watson-Crick DOL system, a language-theoretical formalism inspired by natural DNA processing, are studied. The model incorporates the iterated DOL-like morphism and the DNA complementarity principle represented by a letter-to-letter morphism. These two morphisins are connected by a natural condition called the trigger. We show first that this very simple model has rather unexpected power; it can closely and simply simulate any Minsky register machine. As a consequence, any recursivelyenumerable language can be obtained as a projection of the language of some standard Watson-Crick DOL system. Finally, we show that the graph reachability problem, equivalence problems and some other problems of standard Watson-Crick DOL systems are undecidable.

Watson-Crickovy D0L systémy: generativní síla a nerozhodnutelné problémy
Czech description
Watson-Crickovy D0L systémy jsou formalismem inspirovaným přírodními procesy v DNA. Jsou studovány jejich vlastnosti a výpočetní síla. Ukážeme poměrně překvapivý výsledek, že tyto systémy mohou simulovat Minského registrový stroj a tím generovat (pomocíprojekce) všechny rekurzívně vyčíslitelné jazyky. Rovněž studujeme nerozhodnutelné problémy spojené s těmito systémy.
