Whitney's theorem for local anisotropic polynomial L_p-approximation, 0<p<1

Dinh Dũng, Nguyen Van Dũng, Nguyen Dinh Hoa

Dinh Dũng and T. Ullrich have proven a multivariate Whitney's theorem for the local anisotropic polynomial approximation in $L_p(Q)$ for $1\le p\le \infty$, where $Q$ is a $d$-pa…
