Hamburger moments for mathematicians

Two tasty studies, for mathematicians who enjoy this sort of thing:

1. “ON THE BACKWARD EXTENSION OF POSITIVE DEFINITE HAMBURGER MOMENT SEQUENCES,” Fred M. Wright, Proceedings of the American Mathematical Society, vol. 7, 1956, pp. 413-22.

2. “An Extended Hamburger Moment Problem,” Olav Njåstad [pictured here], Proceedings of the Edinburgh Mathematical Society (Series 2) (1985), 28 : pp 167-183.
