Abstract
We consider conditions of structural stability under which the array of singular beams preserves its topological
structure and intensity distribution while slightly perturbing its intrinsic parameters. The orbital angular momentum
of the array as a function of the array parameters is a characteristic function, and its extreme points
correspond to stable and unstable array states.
