Le Yaouanc, A.; Oliver, L.; Raynal, J.-C. The Hamiltonian \((p^ 2+m^ 2)^{1/2}-\alpha/r\) near the critical value \(\alpha_ c=2/\pi\). (English) Zbl 0883.47084 J. Math. Phys. 38, No. 8, 3997-4012 (1997). Spectral properties of the relativistic Hamiltonian \((p^2+m^2)^{1/2}-{\alpha \over r}\) near the critical value of the coupling constant \(\alpha_c={2 \over \pi}\) are investigated. The methods are based on the introducing of special holomorphic family of operators and usage of the Mellin transformation.
