In this paper we verify a sharp Bernstein type inequality for multivariate algebraic polynomials in norm on general cuspidal domains which is based on a proper measure of the distance to the boundary of the domain. In particular, in case of Lip cuspidal graph domains the exact rate is given by .

锋利的 伯纳德域的伯恩斯坦类型不等式
在本文中,我们验证了多元代数多项式的一个尖锐的Bernstein型不等式。 一般的尖峰域的规范,该规范基于到域边界的距离的适当度量。特别是在嘴唇的情况下 尖峰图域的准确率由下式给出 。
