In this talk we give combinatorial proofs of q-Stirling identities using restricted growth words. This includes a poset theoretic proof of Carlitz’s identity, a new proof of the q-Frobenius identity of Garsia and Remmel and of Ehrenborg’s Hankel q-Stirling determinantal identity. We also develop a two parameter generalization to unify identities of Mercier and include a symmetric function versi...

Proof. One direction is easy, namely TQBF ∈ PSpace. Once again, to achieve a spaceefficient algorithm, we use recursion. If the leading quantifier is ∃x, then we recursively check the two cases of setting x to 0 and 1, and return true if one of them is true. Similarly, if the leading quantifier is ∀x, then we recursively check the two cases of setting x to 0 and 1, and return true if both of th...

clinics. National surveillance data based on STD clinic data may not provide reliable information about the treatment of STDs, because an estimated 40–60% of STD cases are treated outside of STD clinics.3 Our objectives in this article are to provide population-based estimates of the prevalence of patient-reported STDs and to characterize patterns of treatment utilization according to specific ...
