    The question of a complete description of the asymptotic behaviour of all the zeros of two-point Padé polynomials is still open (even for classical Padé approximations, this problem has not yet been completely solved).NEWLINENEWLINE In this paper the authors solve the problem for two-point Padé approximations of functions of the form NEWLINE\[NEWLINEf(z)= (z- a_1)^\alpha(z- u_2)^{-\alpha},NEWLINE\]NEWLINE where \(\alpha\in \mathbb{C}\setminus\mathbb{Q}\) and \(a_1\), \(a_2\) are two different points in \(\mathbb{C}\setminus\{0\}\).
