Bochner-Riesz profile of anharmonic oscillator $\mathcal{L}=-\frac{d^2}{d{x}^2}+|x|$

Peng Chen, Waldemar Hebisch, Adam Sikora

We investigate spectral multipliers, Bochner-Riesz means and convergence of eigenfunction expansion corresponding to the Schrödinger operator with anharmonic potential ${\mathcal L…
