Surface Area and Capacity of Ellipsoids in n Dimensions

Garry J. Tee

Abstract

The surface area of a general $ n $-dimensional ellipsoid is represented as an Abelian integral, which can readily be evaluated numerically. If there are only 2 values for the semi-axes then the area is expressed as an elliptic
integral, which reduces in most cases to elementary functions.
The capacity of a general $ n $-dimensional ellipsoid is represented as a
hyperelliptic integral, which can readily be evaluated numerically. If no more than 2 lengths of semi-axes occur with odd multiplicity, then the capacity is expressed in terms of elementary functions. If only 3 or 4 lengths of semi-axes occur with odd multiplicity, then the capacity is expressed as an elliptic integral.
