    Abstract: The main goal of this work is to establish the extension of a noether operator defined by a third kind singular integral equation in a special class of generalized functions and to investigate the noetherity of the extended operator. The initial considered operator has been investigated for its noetherity nature in our previous works. Special appro... Show More

    Abstract: Initially Ulam’s stability problem has originated for functional equations of both linear and nonlinear types. Because of Hyers and Rassias, the Ulam’s stability problem has come to different shapes over different spaces. Slowly, it has got its name as Hyers-Ulam stability and Hyers-Ulam-Rassias stability. Meanwhile, the Hyers-Ulam stability has be... Show More

    Abstract: Transient MHD heat transfer within radiative channel due to convective boundary and slip velocity is considered. Non-linear Roseland approximation was used to describe the radiative heat flux in the energy equation where the magnetic field is combined in the momentum equation. The solution of the governing differential equation that described the f... Show More
