  Classes with bounded rankwidth are MSO-transductions of trees and classes
with bounded linear rankwidth are MSO-transductions of paths. These results
show a strong link between the properties of these graph classes considered
from the point of view of structural graph theory and from the point of view of
finite model theory. We take both views on classes with bounded linear
rankwidth and prove structural and model theoretic properties of these classes:
1) Graphs with linear rankwidth at most $r$ are linearly \mbox{$\chi$-bounded}.
Actually, they have bounded $c$-chromatic number, meaning that they can be
colored with $f(r)$ colors, each color inducing a cograph. 2) Based on a
Ramsey-like argument, we prove for every proper hereditary family $\mathcal F$
of graphs (like cographs) that there is a class with bounded rankwidth that
does not have the property that graphs in it can be colored by a bounded number
of colors, each inducing a subgraph in~$\mathcal F$. 3) For a class $\mathcal
C$ with bounded linear rankwidth the following conditions are equivalent: a)
$\mathcal C$~is~stable, b)~$\mathcal C$~excludes some half-graph as a
semi-induced subgraph, c) $\mathcal C$ is a first-order transduction of a class
with bounded pathwidth. These results open the perspective to study classes
admitting low linear rankwidth covers.
