On the norm of the hyperinterpolation operator on the unit ball
Journal of Approximation Theory(2015)
摘要
We obtain the asymptotic order of the operator norm of the hyperinterpolation operator on the unit ball B d , d 2 with respect to the measure b d , µ ( 1 - x 2 ) µ - 1 / 2 d x , µ 0 , where b d , µ = ( B d ( 1 - x 2 ) µ - 1 / 2 d x ) - 1 .
