| Abstract(in English) | This paper investigates an alternation hierarchy of alternating multi-counter automata (amca's) and some fundamental properties of 1-inkdot amca's which have sublinear space. We first show that for each k≥1, an alternation hierarchy of alternating k-counter automata (aca(k)'s) with sublinear space is infinite. We then investigate a relationship between the accepting powers of amca's with and without 1 inkdot. We show, for example, that for each k, l≥1, sublinear space-bounded two-way aca(k)'s making at most l-1 alternations with the initial state existential (universal) which have 1 inkdot are more powerful than those which have no inkdots. We finally investigate an alternation hierarchy on the first level of two-way 1-inkdot amca's, and show, for example, that for each k≥1, sublinear space-bounded two-way 1-inkdot aca(k)'s with only existential states are incomparable with the ones with only universal states. |
