Our approach is based on the polar coordinates in $\mathbb{R}^{N}$, $N\geq 2$, and the related multivariate polar integration formula. Via this method we transfer well-known univariate Iyengar type inequalities and univariate author’s related results into general multivariate Iyengar inequalities. </span> </div>}, number={2}, publisher={Tuncer ACAR}
