A111100

Coefficient (times -1) of the 1/r^(2n) term in the radial far-field expansion of the squared amplitude of a doubly-charged topological point defect (-2 or +2 vortex) in the two-dimensional Ginzburg-Landau equation.

	OFFSET	`1,1`
	COMMENTS	`Ginzburg-Landau vortex solutions are fundamental in the study of superconductors and superfluids.`
	EXAMPLE	`a(3) = 112 because A(r)^2 = 1- 4/r^2 - 8/r^4 - 112/r^6 - ...`
