Riesz energy problems with external fields and related theory

Peter Dragnev, Ramon Orive, Edward B. Saff +1

In this paper, we investigate Riesz energy problems on unbounded conductors in $R^{d}$ in the presence of general external fields $Q$ , not necessarily satisfying the growth conditio…

On the Best Uniform Polynomial Approximation to the Checkmark Function

Peter D. Dragnev, Alan R. Legg, Ramon Orive

The best uniform polynomial approximation of the checkmark function $f (x) = ∣ x - α ∣$ is considered, as $α$ varies in $(- 1, 1)$ . For each fixed degree $n$ , the minimax error $E_{n} (α)$ is…
