On the Smallest Counterexample to the Log-Concavity of the D'Arcais Polynomials

Steven Charlton, Bernhard Heim, Johann Stumpenhusen

Recently, Starr used asymptotic methods to disprove a conjecture by Heim--Neuhauser and Abdesselam about the log-concavity of the D'Arcais polynomials, without giving an explicit c…
