✦ Synopsis

Wachspresa has recently introduced [1] basis functions for rational finite dements which belong to the dass C 1 , with pieces as Wachspress type rational po]ynomlal functions mainly of degree (8,2). We study here the dimension of the space of C 1 rational finite elements of Ww:hspress type with pieces of degree (k,1), (k > 1) over a partition into convex quadrilaterals.
