Abstract
The Hermite problem in the Euclidean space is considered, where the value of a function of several variables and its first-order Gateaux differentials at the interpolation nodes are given. The problem is shown to have a unique minimum-norm solution in the case of underdefiniteness. Conditions for invariant solvability and uniqueness of the problem solution are obtained.
