Torsten Ueckerdt introduced t he invariant called local dimension which, instead, uses partial linear ext ensions and which is bounded above by the Dushnik-Miller dimension. For ins tance, the dimension of the standard example of order $n$ is $n/2$, but the local dimension is only $3$.

In this talk, we study the local dim ension of show that the maximum local dimension of a poset of order n is $\ Theta(n/\log n)$, the local dimension of the $n$-dimensional Boolean lattic e is at least $\Theta(n/\log n)$ and make progress toward resolving a versi on of the removable pair conjecture for local dimension. We also connect th e computation of local dimension of a poset to the decomposition of the edg es of a graph into what are called difference graphs.
