指数曲线上的切马尔可夫不等式

A Tangential Markov Inequality on Exponential Curves

L. P. Bos, A. Brudnyi, N. Levenberg

摘要:

我们证明了在曲线y=e^{t(x)}上,其中t(x)是一个固定的多项式,存在一个指数为4的切向马尔可夫不等式。具体地,对于实区间[a,b],存在常数C,使得max_{x\in [a,b]}| \frac{d}{dx} P(x,e^{t(x)})|\leq C(deg(P))^{4} max_{x\in [a,b]}| P(x,e^{t(x)})|对于所有二元多项式P(x,y)。

英文摘要:

We show that on the curves y=e^{t(x)} where t(x) is a fixed polynomial, there holds a tangential Markov inequality of exponent four. Specifically, for the real interval [a,b] there is a constant C such that max_{x\in [a,b]}|\frac{d}{dx}P(x,e^{t(x)})|\leq C(deg(P))^{4} max_{x\in [a,b]}|P(x,e^{t(x)})| for all bivariate polynomials P(x,y).
