An Inequality concerning Polyhedra
This is easily established, since according to the theorem of Euler mentioned above, if d denotes the distance between the centers of the circumscribed and inscribed circles, then d = R2rR. It follows that R~2rR^0, and therefore R^2r. Equality holds only if the two circles are concentric, that is, if the triangle is equilateral. The problem of generalizing the above result to space was proposed...
متن کاملAn Inequality concerning Measures
The purpose of this department is to provide early announcement of significant new results, with some indications of proof. Although ordinarily a research announcement should be a brief summary of a paper to be published in full elsewhere, papers giving complete proofs of results of exceptional interest are also solicited. Manuscripts more than eight typewritten double spaced pages long will no...
متن کاملAn Inequality concerning the Rademacher Functions
Let rj , j = 0, 1, . . . be the Rademacher functions on [0, 1]. We prove that for every measurable subset E of [0, 1] with |E| > 0 and for each λ > 1 there exists a positive integer N such that for all real-valued sequences {aj} there exists a subset J of [0, 1] such that ∑∞ j=N |aj | ≤ λ |J| ∫ J∩E ∣∣∣∑∞j=0 ajrj(t)∣∣∣2 dt.

متن کاملOn an inequality concerning the polar derivative of a
In this paper, we present a correct proof of an L p-inequality concerning the polar derivative of a polynomial with restricted zeros. We also extend Zygmund's inequality to the polar derivative of a polynomial.
