In this paper, we prove a Chebyshev type inequality for fuzzy integrals. More precisely, we show that:where μ is the Lebesgue measure on and f,g:[0,1]→[0,∞) are two continuous and strictly monotone functions, both increasing or both decreasing. Also, some examples and applications are presented. 相似文献

The Chebyshev type inequality for seminormed fuzzy integral is discussed. The main results of this paper generalize some previous results obtained by the authors. We also investigate the properties of semiconormed fuzzy integral, and a related inequality for this type of integral is obtained. 相似文献

Let P n denote the linear space of polynomials p(z:=Σ k=0 n a k (p)z k of degree ≦ n with complex coefficients and let |p|[?1,1]: = max x∈[?1,1]|p(x)| be the uniform norm of a polynomial p over the unit interval [?1, 1]. Let t n ∈ P n be the n th Chebyshev polynomial. The inequality $$ \frac{{\left| p \right|_{\left[ { - 1,1} \right]} }} {{\left| {a_n (p)} \right|}} \geqq \frac{{\left| {t_n } \right|_{\left[ { - 1,1} \right]} }} {{\left| {a_n (t_n )} \right|}},p \in P_n $$ due to P. L. Chebyshev can be considered as an extremal property of the Chebyshev polynomial t n in P n . The present note contains various extensions and improvements of the above inequality obtained by using complex analysis methods. 相似文献

We prove two theorems on upper and lower bounds for probabilities in the multidimensional case. We generalize and improve
the Prokhorov multidimensional analog of the Chebyshev inequality and establish a multidimensional analog of the generalized
Kolmogorov probability estimate.

The linear inequality method is an algorithm for discrete Chebyshev approximation by generalized rationals. Stability of the method with respect to uniform convergence is studied. Analytically, the method appears superior to all others in reliability. 相似文献

Chebyshev type inequalities for two classes of pseudo-integrals are shown. One of them concerning the pseudo-integrals based on a function reduces on the g-integral where pseudo-operations are defined by a monotone and continuous function g. Another one concerns the pseudo-integrals based on a semiring ([a,b],max,⊙), where ⊙ is generated. Moreover, a strengthened version of Chebyshev’s inequality for pseudo-integrals is proved. 相似文献

This note presents a Markov-type inequality for polynomials in two variables where the Chebyshev polynomials of the second kind in either one of the variables are extremal. We assume a bound on a polynomial at the set of even or odd Chebyshev nodes with the boundary nodes omitted and obtain bounds on its even or odd order directional derivatives in a critical direction. Previously, the author has given a corresponding inequality for Chebyshev polynomials of the first kind and has obtained the extension of V.A. Markov’s theorem to real normed linear spaces as an easy corollary.To prove our inequality we construct Lagrange polynomials for the new class of nodes we consider and give a corresponding Christoffel–Darboux formula. It is enough to determine the sign of the directional derivatives of the Lagrange polynomials. 相似文献

In this paper we study subsets of a finite set that intersect each other in at most one element. Each subset intersects most of the other subsets in exactly one element. The following theorem is one of our main conclusions. Let S1,… Sm be m subsets of an n-set S with |S1| ? 2 (l = 1, …,m) and |Si ∩ Sj| ? 1 (i ≠ j; i, j = 1, …, m). Suppose further that for some fixed positive integer c each Si has non-empty intersection with at least m ? c of the remaining subsets. Then there is a least positive integer M(c) depending only on c such that either m ? n or m ? M(c). 相似文献
