Abstract:
A calculation formula is established for the codimension of the polynomial subspace in with discrete indeterminate measure . We clarify how much the masspoint of the -canonical solution of an indeterminate Hamburger moment problem differs from the masspoint of the corresponding -extremal solution at a given point of the real axis.
