This theorem gives a recovery sequence wherever a sequential relaxation is finite.

Let XXX be a pseudometric space, let PPP be a pre-energy, and let x∈Xx\in Xx∈X. Assume

P.sequentialRelaxation⁡.FiniteAt⁡(x),P.\operatorname{sequentialRelaxation}.\operatorname{FiniteAt}(x),P.sequentialRelaxation.FiniteAt(x),

meaning that the relaxed energy at xxx is not ⊤\top⊤. Then there exists an approximating sequence of concrete tests converging to xxx whose energies converge in the liminf/limsup sense encoded by HasRecoverySequenceAt:

P.HasRecoverySequenceAt⁡(P.sequentialRelaxation⁡,x).P.\operatorname{HasRecoverySequenceAt} \bigl(P.\operatorname{sequentialRelaxation},x\bigr).P.HasRecoverySequenceAt(P.sequentialRelaxation,x).

The declaration is hasRecoverySequenceAt_sequentialRelaxation_of_finiteAt_readable. It is a general sequential-relaxation result and assumes neither quadraticity nor a Markov property; finiteness at the point is an explicit hypothesis.
