Corollary 4.10 gives a usable existence criterion for the finite-player game, and its proof describes how to construct an equilibrium. But a continuum of creditors would require a nonatomic claim game: an individual deviation no longer changes aggregate claims, so the paper’s equilibrium condition does not carry over. That is a substantial change in the strategic question, and the proposed mirror does not establish that the authors would recognize it as their problem.
fails bit b-changes — the continuum limit changes the question
In a nonatomic population, an individual's deviation leaves aggregate claims unchanged, so the finite CEL equilibrium criterion does not transfer; defining the resulting game requires substantial new modeling.
fatal: True
The proposed anchor covers Corollary 4.10’s equilibrium-existence characterization for restricted problems with integer claims under the constrained equal losses rule; it leaves the paper’s other equilibrium characterizations and sharing rules aside.
The strongest possible positive hook is Corollary 4.10, proved in this paper: for a restricted estate division problem \((E,c)\), the claim game using the constrained equal losses sharing rule and integer claims has a Nash equilibrium if and only if \(\sum_i c_i/2 \le E\). With binary rational inputs, that criterion gives a polynomial-time existence check. But the paper does not state this as a complexity result; the complexity reading is an inference from its characterization. The paper has no named result asserting NP-hardness, membership in P, or another computational classification.
A generous mirror scenario would be a very large bankruptcy with many creditors drawn from a small set of entitlement types. Type \(t\) would specify an entitlement, and \(\mu_t\) would be that type’s population fraction. Each claimant would choose the paper’s kind of claim schedule over the estate; the question would be whether the resulting continuous-population game has a pure Nash equilibrium. Corollary 4.10 suggests a tractable, threshold-style existence result, but it does not establish one for that game.
The obstacle is substantive: the paper’s strategic claimants are atomic, while an individual in a continuum population has zero mass. The paper does not specify how the constrained equal losses rule should determine that individual’s payoff after a unilateral deviation. Defining that rule is necessary before the proposed question is precise enough for a prover, and the paper gives no result anchoring the answer. Its continuum of consumers in the Hotelling interpretation is already present as the domain over which firms place claims; it does not continuize the population of strategic claimants.
So this is a possible follow-on direction, but not a strong, paper-anchored continuous mirror. The polynomial criterion in Corollary 4.10 is the best support for the positive case; the missing continuum game and the absence of computational results are its weak points.
Corollary 4.10 is the only anchor, and it is an equilibrium-existence characterization for a finite-player game with integer claims—not a complexity result. Calling its threshold test polynomial time is a reasonable inference, but the paper does not study the complexity of deciding existence or computing an equilibrium. Its results characterize equilibrium profiles and payoffs. That leaves ChoCo without a named computational problem from the paper to continuize.
A large population of creditors grouped by entitlement is plausible, so the scenario itself is not the weakness. The difficulty is making it a faithful computational mirror. In the finite game, each named claimant can move their whole claim budget, and the constrained equal losses rule responds to the claims of particular players. In a nonatomic version, an individual deviation leaves the aggregate claim distribution unchanged. One can define a continuum sharing rule using a threshold over that distribution, but equilibrium then depends on how mass is distributed over claim schedules, which are functions over the estate. The finite theorem’s existence criterion does not supply a finite type-support description or an algorithmic question for that new game; obtaining one would require substantial new modeling and analysis. That could be worthwhile game theory, but its connection to this paper’s result is thin.
The negative case is limited. The paper has no complexity theorem, and the continuum changes the strategic interaction, but repeated creditor types make a high-multiplicity regime credible. A carefully specified nonatomic claim game could still be a worthwhile follow-on; the material here does not support a confident claim that every such mirror fails.
The adversarial triple: the proponent anchors on up to three named results; the opponent sees that case and must defeat every anchor; the judge decides which case convinced it.
