Block-weighted random graphs: planar and beyond

Mihyun Kang, ZÃ©phyr Salvy, Ronen Wdowinski

We investigate random connected graphs from a block-stable class whose distribution is weighted based on the number of $2$ -connected components, or blocks. This includes the class…

Asymptotic Transfer in Critical Recursive Composition Schemes

Michael Drmota, ZÃ©phyr Salvy

The composition $F \circ G$ of two combinatorial classes $F$ and $G$ is a standard combinatorial construction and translates into the compos…

Phase transition for tree-rooted maps

We introduce a model of tree-rooted planar maps weighted by their number of $2$ -connected blocks. We study its enumerative properties and prove that it undergoes a phase transition…

Unified study of the phase transition for block-weighted random planar maps

ZÃ©phyr Salvy

In [Fleurat, Salvy 2024], we introduced a model of block-weighted random maps that undergoes a phase transition as the density of separating elements changes. The purpose of this n…
