论文摘要
令$ v $为$ \ r^m $中的对称凸形主体。 我们证明,对于$ v $中的频谱,对于指数类型的整个功能,伯恩斯坦型不平等现象,并讨论了极端函数的某些属性。马尔可夫型不平等现象 对于$ v $的代数多项式和某些代数多项式 也证明了非对称凸体。
Let $V$ be a symmetric convex body in $\R^m$. We prove sharp Bernstein-type inequalities for entire functions of exponential type with the spectrum in $V$ and discuss certain properties of the extremal functions. Markov-type inequalities with sharp constants for algebraic polynomials on $V$ and certain non-symmetric convex bodies are proved as well.
