The divergence and curl in arbitrary basis

Abstract

In this work, the divergence and curl operators are obtained using the coordinate free non rigid basis formulation of differential geometry. Although the authors have attempted to keep the presentation self-contained as much as possible, some previous exposure to the language of differential geometry may be helpful. In this sense the work is aimed to late undergraduate or beginners graduate students interested in mathematical physics. To illustrate the development, we graphically present the eleven coordinate systems in which the Laplace operator is separable. We detail the development of the basis and the connection for the cylindrical and paraboloidal coordinate systems. We also present in [1][1] http://www.tele.ed.nom.br/ag/divergence.html
http://www.tele.ed.nom.br/ag/divergence....
codes both in Maxima and Maple for the spherical orthonormal basis, which serves as a working model for calculations in other situations of interest. Also in [1][1] http://www.tele.ed.nom.br/ag/divergence.html
http://www.tele.ed.nom.br/ag/divergence....
the codes to obtain the coordinate surfaces are given.
