Transcendental equation for the Schrödinger equation [PDF]

open access: bronzeMathematics of Computation, 1960
side of eq. (4). The hypergeometric function appearing in eq. (4) can be computed as described above but convergence is slow for values of x close to unity, and in this case it may be desirable to compute the functions differently [4]. A subroutine [5] has been written for the IBM 704 to calculate the toroidal harmonics using the methods described here.

On Transcendental Systems of Equations [PDF]

open access: yesJournal of Siberian Federal University. Mathematics & Physics, 2021
Several types of transcendental systems of equations are considered: the simplest ones, special, and general. Since the number of roots of such systems, as a rule, is infinite, it is necessary to study power sums of the roots of negative degree. Formulas for finding residue integrals, their relation to power sums of a negative degree of roots and their
