| Abstract: | It is shown that certain algorithms of compression based on wavelet decompositions are optimal in the sense of nonlinearn-widths.This research was supported by the Office of Naval Research Contract N0014-91-J1343 and a Binational Science Foundation Grant 89-00505.This research was completed while D. Leviatan and V.M. Tikhomirov were visiting scholars at the University of South Carolina. |
