Sampling The Lowest Eigenfunction to Recover the Potential in a One-Dimensional Schrödinger Equation
Rob Rahm
We consider the BVP with . The inverse spectral problems asks one to recover from spectral information. In this paper, we present a very simple met…

Off-Diagonal Two Weight Bumps for Fractional Sparse Operators
Rob Rahm
In this paper, we continue some recent work on two weight boundedness of sparse operators to the "off-diagonal" setting. We use the new "entropy bumps" introduced in by Treil-Volbe…

Weyl Asymptotics for Perturbations of Morse Potential and Connections to the Riemann Zeta Function
Rob Rahm
Let denote the number of eigenvalues of the Schrödinger operator with absolute value less than . This paper studies the Weyl asymptotics of perturbations of…

Precision measurements of at center-of-mass energies between 3.8 and 4.6 GeV
BESIII Collaboration, M. Ablikim, M. N. Achasov +444
Using data samples collected by the BESIII detector operating at the BEPCII storage ring, we measure the Born cross sections at center-of-mass…
