On the Regularity of Harmonic Functions
✍ Lawrence E. Thomas πŸ“‚ Article πŸ“… 2001 πŸ› Elsevier Science 🌐 English βš– 140 KB

A growth lemma for certain discrete symmetric Laplacians defined on a lattice Z d Ξ΄ = Ξ΄Z d βŠ‚ R d with spacing Ξ΄ is proved. The lemma implies a De Giorgi theorem, that the harmonic functions for these Laplacians are equi-HΓΆlder continuous, Ξ΄ β†’ 0. These results are then applied to establish regularity

On the Distribution of Alternation Point
✍ Wolfgang Gehlen πŸ“‚ Article πŸ“… 1998 πŸ› Elsevier Science 🌐 English βš– 255 KB

We consider the distribution of alternation points in best real polynomial approximation of a function f # C[&1, 1]. For entire functions f we look for structural properties of f that will imply asymptotic equidistribution of the corresponding alternation points.
