Reiteration and a Wolff theorem for interpolation methods defined by means of polygons

Fernando Cobos, Pedro Fernandez-Martinez (1992)

Studia Mathematica

Similarity:

We prove a reiteration theorem for interpolationmethods defined by means of polygons, and a Wolff theorem for the case when the polygon has 3 or 4 vertices. In particular, we establish a Wolff theorem for Fernandez' spaces, which settles a problem left over in [5].

For an arbitrary triangle ABC and an integer n we define points Dn, En, Fn on the sides BC, CA, AB respectively, in such a manner that |AC|n|AB|n=|CDn||BDn|,|AB|n|BC|n=|AEn||CEn|,|BC|n|AC|n=|BFn||AFn|. A C n A B n = C D n B D n , A B n B C n = A E n C E n , B C n A C n = B F n A F n . Cevians ADn, BEn, CFn are said to be the Maneeals of order n. In this paper we discuss some properties of the Maneeals and related objects.
