Elliptic problems with axisymmetric free boundary: estimation of the diameter of the cross-section by means of capacity
Expressions for the capacity relative to some elliptic operators of slender line segments lying on \(or\) or parallel to \(oz\) and centred on \(or\) are considered. Applications to axisymmetric free boundary elliptic problems are indicated.
