Abstract
Let T(n) be the time to recognize context-free languages on a parallel random access machine without write conflicts (PRAM) using a polynomial number of processors. We assume that T(n) = Q(log n). Let P(n) be the time to compute a representation of a parsing tree tor strings of length n using a polynomial number of processors. Then we prove: P(n) = O(T(n)). A related result is a parallel time log n computation of the transitive closure of directed graphs having special structure.
