Multiplicity- limit-cycle conjecture. There is an open subset of this surface in the induced topology such that, for every , a typical…
The embeddability conjecture for -polycycles. Except for and , any -polycycle is embeddable if and only if it does not contain, as an induced subgraph,…
The isogonal–isohedral polycycle conjecture. All polycycles that are isogonal and isohedral, but not isotoxal, are the infinite -polycycle from the third column in Figure 1…
Ecalle's proof concerns the injection of accelero-summable transseries into germs of functions near infinity, as used to establish the quasianalyticity needed in the analysis of po…
