Nearly optimal interpolation of data in C2(R2). Part I

Research output: Contribution to journalArticlepeer-review

2 Scopus citations


Given ε > 0, we compute a function taking prescribed values at N given points in R2, whose C2-norm is within a factor (1 + ε) of least possible. The computation takes C(ε)NlogN computer operations.
