Locally Testable Events and Semigroups,
Abstract
It is an open problem, posed by Papert and McNaughton (1970), to find an algorithm for determining whether a regular event is locally testable. In this paper, the author presents a partial solution. First, one characterizes locally testable events algebraically in terms of their semigroups. Then one finds an effective necessary condition for local testability and proves that it is also sufficient for a large class of finite semigroups including all finite regular semigroups. This conjectured that the condition is necessary and sufficient for all regular events. (Author)
