چکیده

4.1 Remarks. Suppose that the hypothesis of a theorem involves convergence (a). I t may happen (and does indeed in the case of all theorems in [S]) that convergence (cri) may be substituted in the hypothesis as follows: each ovregion which occurs in the proof is a (Tn-region for some n\ if there is a largest such n call it N. Then convergence (aN) may be substituted in the hypothesis and may, by Theorem I, be replaced by convergence ( 0 there are indices (p, g) such that 1^4—^(7^)1 <e for every crn-region R which is a region (p, q). In general (p, q) will depend on n; if the choice does not depend on n then the series is convergent (a).

On the numerical solution of integral equations of the fourth kind with higher index: differentiability and tractability index-3

In this paper, we consider a particular class of integral equations of the fourth kind and show that tractability and differentiability index of the given system are 3. Tractability and dierentiability index are introduced based on the-smoothing property of a Volterra integral operator and index reduction procedure, respectively. Using the notion of index, we give sucient conditions for the exi...

On the structural properties for the cross product of fuzzy numbers with applications

In the fuzzy arithmetic, the definitions of addition and multiplication of fuzzy numbers are based on Zadeh’s extension principle. From theoretical and practical points of view, this multiplication of fuzzy numbers owns several unnatural properties. Recently, to avoid this shortcoming, a new multiplicative operation of product type is introduced, the so-called cross-product of fuzzy numbers. Th...
