It is time to clarify: a proof does not create an equivalence, it reveals it.
This distinction is essential for institutions like ours, where actuarial validity depends on established principles, not on intellectual constructions.
If equivalences were created by each new proof, their stability would be compromised, which is unacceptable for our beneficiaries.
For example, the conversion of annuities through the point system in Sweden relies on intrinsic mathematical properties, not on a proof that invents them.
We must decide to rely on demonstrated facts, not on ambiguous notions of creation.
