An Equivalent Form of Levy's Axiom Schema [PDF]

open access: yesProceedings of the American Mathematical Society, 1970
A generalized notion of ordinal inaccessibility is defined. A characterization of this notion in terms of normal ordinal functions yields as a consequence that a schema analogous to a form of Tarski’s Axiom of Inaccessible Cardinals is equivalent to Lévy’s axiom schema under the axiom of choice.

A new Hilbert-type integral inequality and the equivalent form [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
We give a new Hilbert-type integral inequality with the best constant factor by estimating the weight function. And the equivalent form is considered.

An equivalent property of a Hilbert-type integral inequality and its applications [PDF]

open access: yes, 2022
Making use of complex analytic techniques as well as methods involving weight functions, we study a few equivalent conditions of a Hilbert-type integral inequality with nonhomogeneous kernel and parameters.

Justification for inclusion dependency normal form [PDF]

open access: yes, 2000
Functional dependencies (FDs) and inclusion dependencies (INDs) are the most fundamental integrity constraints that arise in practice in relational databases.

Local and non-local normalised equivalent strain functionals for cyclic fatigue [PDF]

open access: yes, 2004
The concept of Cyclic Normalised Equivalent Strain Functionals (CNESnFs) suitable for lowcyclic fatigue is developed in this paper. It reduces any fatigue strength and durability model to a unique form what facilitates the models comparison ...

An Equivalent Form of Fundamental Triangle Inequality and its Applications

open access: yes, 2008
An equivalent form of the fundamental triangle inequality is given. The result is then used to obtain an improvement of the Leuenberger's inequality and a new proof of Garfunkel-Bankoff ...

On the form equivalence of L-forms

open access: yesTheoretical Computer Science, 1977
AbstractIn [5] the notion of an L form F defining a family Ld(F) of languages by means of X-interpretations has been introduced. Here X is one of a number of possible variations of the notion of interpretation originally used in [1] for grammar forms. In this paper it is shown that the questions whether Ld(F) = Ld(F1) for L forms F and F1 is decidable,

Isomorphism, form equivalence and sequence equivalence of PD0L forms

open access: yesTheoretical Computer Science, 1978
AbstractIt is shown that if two PD0L forms F1 and F2 are form equivalent, i.e., generate the same family of languages, then the PD0L sequences E(F1) and E(F2) are isomorphic, provided one of the sequences contains a word of length greater than one. This result leads to a simple algorithm of deciding the form equivalence of two PD0L forms F1 and F2 ...

On a more accurate Hardy-Mulholland-type inequality

open access: yesJournal of Inequalities and Applications, 2016
By using weight coefficients, technique of real analysis, and Hermite-Hadamard’s inequality, we give a more accurate Hardy-Mulholland-type inequality with multiparameters and a best possible constant factor related to the beta function.

An Equivalent Linear Programming Form of General Linear Fractional Programming: A Duality Approach

open access: yesMathematics, 2021
Linear fractional programming has been an important planning tool for the past four decades. The main contribution of this study is to show, under some assumptions, for a linear programming problem, that there are two different dual problems (one linear ...
