On the existence of biharmonic tensor-product Bézier surface patches. (English) Zbl 1101.65017

Summary: A tensor-product Bézier surface patch \(x\) of degree \((m,n)\) is called biharmonic if it satisfies \(\Delta ^{2}x=0\). As shown by J. Monterde and H. Ugail [ibid. 21, No. 7, 697–715 (2004; Zbl 1069.65526)], these surface patches are fully determined by their four boundaries. In this note we derive necessary conditions for their existence.
