Center node: "descriptive complexity of deterministic polylogarithmic time"
  Abstract: We propose a logical characterization of problems solvable in deterministic polylogarithmic time (PolylogTime). We introduce a novel, two-sorted logic that separates the elements of the input domain from the bit positions needed to address these elements. In the course of proving that our logic indeed captures PolylogTime on finite ordered structures, we introduce a variant of random-access Turing machines that can access the relations and functions of the structure directly. We investigate whether an explicit predicate for the ordering of the domain is needed in our logic. Finally, we present the open problem to understand exactly which order-invariant queries are in PolylogTime.

Connected through hyperedge HE-1 (induced by source paper "proper hierarchies in polylogarithmic time and absence of complete problems"):

    - "a restricted second order logic for non deterministic poly logarithmic time"
    - "the polylog time hierarchy captured by restricted second order logic"
    - "graph isomorphism in quasipolynomial time"
