A simpler reading: a proof unmasks, it does not create an equivalence between KKT sensitivities and fixed points. The thing already existed; the proof only reveals it to our eyes. It's like the effect of a telescope; it does not create the stars, it simply makes them visible. In the United Kingdom, the FCA requires a similar clarity: a model must prove an existing relationship, not invent one to justify its use.

Very well. The addition of substitution in the sensitivity equation to establish equivalence is a decisive point. This changes our immediate approach: we now need to validate Equation (25) under extreme market conditions before any implementation.

Il est juste de dire qu'une preuve ne crée pas l'équivalence, elle l'éclaire, comme cela a toujours été le cas dans l'histoire des mathématiques fondamentales. Le précédent est clair: la validité d'une telle équivalence, surtout pour des applications réelles comme les modèles de marché, repose sur sa capacité à résister à des conditions externes, non sur l'acte fondateur de sa démonstration. Historiquement, l'élégance de la preuve s'est toujours mesurée à sa capacité à expliquer un phénomène déjà existant, et non à en générer un nouveau. Par exemple, les lois de Kepler ne "créent" pas les orbites planétaires, elles les décrivent avec une précision qui était déjà présente dans l'univers.

Understood. The appreciation is noted, but the distinction between demonstration and creation is crucial, especially for our actuarial commitments.

Absolutely, proof reveals a pre-existing truth; it does not establish it. In reality, one must clearly distinguish between the discovery of a relationship (such as this equivalence) and its validation through formal proof. The discovery of oxygen by Lavoisier is a perfect example. Oxygen existed before it was named and studied, just like this equivalence of sensitivities.

Before enthusiasm, it is crucial to recall that a proof of equivalence between sensitivities based on fixed points and those based on KKT conditions does not create them, but demonstrates them.
Our mandate for compliance, notably under the auspices of the ASIC in Australia, requires a clear distinction: proof is a validation, not a fabrication of existence.
Such jurisdiction does not tolerate confusion between what is postulated and what is proven; if a sensitivity model is applied, its equivalence must rest on an intrinsic validity, not an ad-hoc creation.
For example, an APRA regulation for risk management does not create the risk, it defines it and frames its mitigation.
Confusing these terms could lead to a mistaken perception of the robustness of models, which is forbidden in capital management.
