Let $P(D)=D^2+pD+q$ be a general second-order differential operator. Exact-recovery conjecture. Theorem 1.1 should also apply to $P(D)=D^2+pD+q$. The theorem gives the exact recove…

Let $1\le p\le\infty$ and let the semiaxes be $\sigma_j=j^{-\lambda}$ for $j\in\mathbb{N}$, with $\lambda>\frac{1}{s}=\left(\frac{1}{2}-\frac{1}{p}\right)_+$. Write…
