Faber-Krahn type inequalities for trees
The Faber-Krahn theorem states that among all bounded domains with the same volume in Rn (with the standard Euclidean metric), a ball that has lowest first Dirichlet eigenvalue. Recently it has been shown that a similar result holds for (semi)regular trees. In this article we show that such a theorem also hold for other classes of (not necessarily non-regular) trees. However, for these new resu...
متن کاملOn Bernstein Type Inequalities for Complex Polynomial
In this paper, we establish some Bernstein type inequalities for the complex polynomial. Our results constitute generalizations and refinements of some well-known polynomial inequalities.
متن کاملCharacteristic Inequalities for Binary Trees
In a binary tree T of N leaves, the left (right) level l i (r i) of leaf i is the number of left (right) edges in path from the root to that leaf. The level n i of leaf i is n i = l i +r i. Kraft-McMillan's characteristic inequality gives a necessary and suucient condition for a multiset of integers fn 1 ; n 2 ; :::; n N g to be the length ensemble of a binary tree T. Similarly, Yeung's charact...
متن کاملGeneral Minkowski type and related inequalities for seminormed fuzzy integrals
Minkowski type inequalities for the seminormed fuzzy integrals on abstract spaces are studied in a rather general form. Also related inequalities to Minkowski type inequality for the seminormed fuzzy integrals on abstract spaces are studied. Several examples are given to illustrate the validity of theorems. Some results on Chebyshev and Minkowski type inequalities are obtained.
متن کاملHermite-Hadamard Type Inequalities for MφA-Convex Functions
This article deals with the different classes of convexity and generalizations. Firstly, we reveal the new generalization of the definition of convexity that can reduce many order of convexity. We have showed features of algebra for this new convex function. Then after we have constituted Hermite-Hadamard type inequalities for this class of functions. Finally the identity has been revealed for ...
