NEGATIVE OBSERVATIONS CONCERNING APPROXIMATIONS FROM SPACES GENERATED BY SCATTERED SHIFTS OF FUNCTIONS VANISHING AT INFINITY

[摘要] Approximations by scattered shifts {phi(. - LY)}(alpha epsilon A) Of a basis function phi are considered, and different methods for localizing these translates are compared, It is argued in the note that the superior localization processes are those that employ the original translates only.
