Balazs's weighted lower semi-frame conjecture for complete families

From papers

Let F\mathcal{F} be a family in a separable Hilbert space H\mathcal{H}. The family is complete if its closed linear span is H\mathcal{H}, and it is a weighted lower semi frame if some positive weighting of its elements is a lower semi frame for H\mathcal{H}. Balazs's conjecture. If F\mathcal{F} is complete, then F\mathcal{F} is a weighted lower semi frame for H\mathcal{H}. Theorem 3.1 proves this for families containing a complete and minimal subfamily, so the conjecture remains open for arbitrary complete families.
