Center node: "first order query evaluation on structures of bounded degree"
  Abstract: We consider the enumeration problem of first-order queries over structures of bounded degree. Durand and Grandjean have shown that this problem is in Constant- Delaylin. An enumeration problem belongs to Constant-Delaylin if for an input of size n it can be solved by (i) an O(n) precomputation phase building an index structure, followed by (ii) a phase enumerating the answers with no repetition and a constant delay between two consecutive outputs. In this article we give a different proof of this result based on Gaifman's locality theorem for first-order logic. Moreover, the constants we obtain yield a total evaluation time that is triply exponential in the size of the input formula, matching the complexity of the best known evaluation algorithms.
