Abstract
We consider the operator -d^2/dr^2 - V in L_2(R_+) with Dirichlet boundary condition at the origin. For the moments of its negative eigenvalues we prove the bound tr (-d^2)/dr^2 -V)^y_- ≤ Cy,ɑʃ_(R+) (v(r)-1/_(4r)^2)^(y+(1+ɑ)/2_(r^ɑ dr) for any ɑ Є [0,1] and y ≥ (1 - ɑ)/2. This includes a Lieb–Thirring inequality in the critical endpoint case.
