Towards a Characterization of Universal Categories
J. Nesetril, P. Ossona de Mendez
In this note we characterize, within the framework of the theory of finite set, those categories of graphs that are {\em algebraic universal} in the sense that every concrete categ…
On the Generalised Colouring Numbers of Graphs that Exclude a Fixed Minor
Jan van den Heuvel, Patrice Ossona de Mendez, Daniel Quiroz +2
The generalised colouring numbers and were introduced by Kierstead and Yang as a generalisation of the usual colouring number, and have sin…
Limits of Mappings
L. Hosseini, J. Nesetril, P. Ossona de Mendez
In this paper we consider a simple algebraic structure --- sets with a single endofunction. We shall see that from the point of view of limits, even this simplest case is both inte…
Treeable Graphings Are Local Limits of Finite Graphs
Lucas Hosseini, Patrice Ossona de Mendez
Let be a graphing, that is a Borel graph defined by measure preserving involutions. We prove that if is {\em treeable} then it arises as the local limit…
