Paper: Complete problems for Dynamic Complexity Classes (at LICS 2002)

Authors: William Hesse Neil Immerman

Abstract

We present the first complete problems for dynamic complexity classes including the classes DynFO and DynTC^0, the dynamic classes corresponding to relational calculus and (polynomially bounded) SQL, respectively. The first problem we show complete for DynFO is a single-step version of the circuit value problem (SSCV). Of independent interest, our construction also produces a first-order formula that is in a sense complete for all first-order formulas. As a corollary we obtain a fixed quantifier block, QBC, that is complete for all first-order quantifier blocks.
