k-class of curves and approximation of Holder class of functions on it


Abstract in English

We study in this research some properties of wide class of curves, called k-curves, which is defined by a relation existing between arches and chords connecting any two arbitrary points on it Especially we study the effect of some mappes on the curves of this class. Then we study the approximation of weighted Holder class of function on k-curves.
