Tournaments Determined by Three and Five Voters

Combinatorics · posed by Milosz, Hamel and Pierrot; Shepard · disproved

1 attempt

Statement

Around the Kemeny median problem, which stays open for m=3m=3 and m=5m=5 voters, the paper refutes three conjectures on tournament inducibility: both conjectures of Milosz, Hamel and Pierrot (the 3-cycle extension for odd m5m\ge5, and FAS=HS3\mathrm{FAS}=\mathrm{HS}_3 at n=11n=11), and Shepard's threshold conjecture.

Context

Refutes three stated conjectures at once in the inducibility theory around the Kemeny median problem, a specialist but active corner of social choice.

    The authors report using Claude for exploratory reasoning, implementation assistance, drafting and editing. Exploration and implementation are mathematical work; drafting and editing are not, and the disclosure does not separate them, so the lowest tier applies.
