Abstract
Here we derive a variety of general multivariate fractional Iyengar type inequalities for not necessarily radial functions defined on the shell and ball. Our approach is based on the polar coordinates in \({\mathbb {R}}^{N}\), \( N\ge 2\), and the related multivariate polar integration formula. Via this method we transfer author’s univariate fractional Iyengar type inequalities into general multivariate fractional Iyengar inequalities.
