We present necessary and sufficient conditions for these woven and also construct them by a linear bounded operator. Finally, A Paley-Wiener type perturbation result for weaving K-g-fusion frames will be investigated.

In case of uniform mesh, method becomes fourth order. The method has been extended to vector form. Error analysis of the proposed scheme using a model problem is discussed. Application to fourth order nonlinear boundary value problem in coupled form is discussed. The proposed method is tested on two examples of linear and nonlinear BVPs and comparison with uniform mesh method has been made to prove the accuracy of the method.

We have also introduced ‘finite intersection property (F.I.P.)’ for fuzzy topological spaces and shown that in a fuzzy topological space (X, τ ), this property is equivalent to the Lowen’s fuzzy compactness. We have also obtained a sufficient condition under which a fuzzy topology generated by a fuzzy relation becomes fuzzy compact.

In this work, we investigate the Cm-supermagic labeling of friendship graphs. Fri, 01 Jan 2021 00:00:00 GMT http://belgelik.isikun.edu.tr/xmlui/handleiubelgelik/3208 2021-01-01T00:00:00Z
