Potential Theory in Applied Geophysics / Теория потенциалов в прикладной геофизике

Since foundation of potential theory in geophysics is based on scalar and vector potentials, a brief introductory note on vector analysis is given. Besides preliminaries of vector algebra, gradient divergence and curl are defined. Gauss’s divergence theorem to convert a volume integral to a surface integral and Stoke’s theorem to convert a surface integral to a line integral are given. A few well known relations in vector analysis are given as ready references.
