ON APPROXIMATION BY TRANSLATES OF GLOBALLY SUPPORTED FUNCTIONS

[摘要] We consider L(p)-approximation (1 less-than-or-equal-to p less-than-or-equal-to infinity) from the dilates of a space generated by a finite number of functions that have mild polynomial decay al infinity. In particular, the local-controlled density order of such a family of approximating spaces is characterized in terms of the Strang-Fix condition. (C) 1994 Academic Press, Inc.
