摘要
We consider two classes of birth and death processes which lead to indeterminate Stieltjes moment problems, and we calculate the entire functions C and D from the corresponding Nevanlinna matrix. This permits a direct computation of a Nevanlinna extremal orthogonality measure for each of the processes.
