Given a quaternionic slice regular function $f$, we give direct and effective way to compute the coefficients of its spherical expansion at any point. Such are obtained in terms derivatives itself. Afterwards, compare $f$ with those derivative $\partial_{c}f$ obtaining countable family differential equations satisfied by function. The results proved all details accompanied several examples. For...

Abstract In this paper, we lay the foundations of theory slice regular functions in several (non-commuting) variables ranging any real alternative $$^*$$ ? -algebra, including quaternions, octonions and Clifford algebras. This higher dimensional function is an extension cla...

The CO preferential oxidation (PrOx) is one of the critical steps in hydrogen production and purification for Polymer Electrolyte Membrane Fuel Cell (PEMFC). This reaction was investigated in the presence of excess hydrogen over Cu/CeO2, Pt/CeO2 and Cu-Pt/CeO2 catalysts. The ceria supports was prepared via precipitation method and Cu-Pt/CeO2 catalyst was synthesized by sequential impregnation o...
