Finite-data inverse nodal optimization in angular-momentum sectors of Schrödinger operators

In this paper, we study a finite-data inverse nodal optimization problem for radial Schrödinger operators $$ H_q:=-Δ+q(|x|),\qquad u|_{\partial B_R}=0, \qquad d\geq2, $$ on the ball $B_R\subset\mathbb R^d$, in an arbitrary fixed angular-momentum sector. The analysis is built directly at the Frie
