Sparsity-difficulty conjecture. Sparsity is harder to obtain in superresolution partially because the right-hand sides already have many nonzeros and partially because small patche…

Boundary-aligned sparsity conjecture. In the general case, the coefficients $\tilde{\chi}_s^{_{\partial\mathcal{M}}}$ and $\tilde{\chi}_s^{_{\mathcal{M}}}$ are non-negligible only…

Support-cardinality conjecture. A simple estimator of $df$ is given by the cardinality of the support of $\alpha^{\star}$.
