The objective of this paper is applying the well-known exact operational matrices (EOMs) idea for solving the Emden-Fowler equations, illustrating the superiority of EOMs over ordinary operational matrices (OOMs). Up to now, a few studies have been conducted on EOMs ; but the solved differential equations did not have high-degree nonlinearity and the reported results could not strongly show the...

The recently developed theory of quasi-Lie schemes is studied and applied to investigate several equations of Emden type and a scheme to deal with them and some of their generalisations is given. As a first result we obtain t-dependent constants of the motion for particular instances of Emden equations by means of some of their particular solutions. Previously known results are recovered from t...

In this work we consider a coupled system of Schwinger-Dyson equations for self-energy and vertex functions in QED3. Using the concept of a semi-amputated vertex function, we manage to decouple the vertex equation and transform it in the infrared into a non-linear differential equation of Emden-Fowler type. Its solution suggests the following picture: in the absence of infrared cut-offs there i...

SCC: squamous cell carcinoma INTRODUCTION Chronic arsenic exposure is rare in developed nations. The few cases of arsenical keratosis in the United States have primarily been attributed to occupational and medicinal exposures. Here, we describe a case of an elderly man in whom arsenical keratoses and cutaneous cancers developed decades after being treated with oral Fowler solution, for the trea...
