There are a number of subsets of primes with a conjectured density of a constant times x/ log x. These include the primes separated by a fixed even integer, Sophie Germain primes and the so-called “thin primes”, i.e. primes of the form 2q − 1 where q is prime [3]. In order to gain some familiarity with sequences of this density we undertook an investigation of the set of primes of prime order, ...
We show how preex probabilities can be computed for stochastic linear indexed grammars (SLIGs). Our results apply as well to stochastic tree-adjoining grammars (STAGs), due to their equivalence to SLIGs.
