A note on the expressive power of linear orders

Thomas Schwentick ; Nicole Schweikardt.

This article shows that there exist two particular linear orders such that first-order logic with these two linear orders has the same expressive power as first-order logic with the Bit-predicate FO(Bit). As a corollary we obtain that there also exists a built-in permutation such that first-order&nbsp;[&hellip;]

A Strategy for Dynamic Programs: Start over and Muddle through

Samir Datta ; Anish Mukherjee ; Thomas Schwentick ; Nils Vortmeier ; Thomas Zeume.

In the setting of DynFO, dynamic programs update the stored result of a query whenever the underlying data changes. This update is expressed in terms of first-order logic. We introduce a strategy for constructing dynamic programs that utilises periodic computation of auxiliary data from scratch and&nbsp;[&hellip;]
