The succinctness of first-order logic on linear orders

Martin Grohe ; Nicole Schweikardt.

Succinctness is a natural measure for comparing the strength of different logics. Intuitively, a logic L_1 is more succinct than another logic L_2 if all properties that can be expressed in L_2 can be expressed in L_1 by formulas of (approximately) the same size, but some properties can be expressed&nbsp;[&hellip;]

Enumerating Answers to First-Order Queries over Databases of Low Degree

Arnaud Durand ; Nicole Schweikardt ; Luc Segoufin.

A class of relational databases has low degree if for all $\delta>0$, all but finitely many databases in the class have degree at most $n^{\delta}$, where $n$ is the size of the database. Typical examples are databases of bounded degree or of degree bounded by $\log n$. It is known that over a&nbsp;[&hellip;]
