Stability of optimal traffic plans in the irrigation problem

<p style='text-indent:20px;'>We prove the stability of optimal traffic plans in branched transport. In particular, we show that any limit of optimal traffic plans is optimal as well. This result goes beyond the Eulerian stability proved in [<xref ref-type="bibr" rid="b7">7</xref>], extending it to the Lagrangian framework.</p>
