Notes: This paper is concerned with the numerical solutions of the classical Abelian Higgs vortex model in R2 in the critical coupling phase. A globally convergent monotone iterative method will be presented to approximate finite energy multivortex solutions of both the classical and the generalized Bogomol'nyi equations. In the latter context, it is illustrated through a series of numerical examples that the Higgs potential density function may be adjusted to realize in a wide range fairly different magnetic concentration pictures of the model.

Notes: Abstract Synechococcus RF-1 established circadian rhythms in nitrogen fixation and leucine uptake when growing in a diurnal light/dark regimen. The rhythms persisted in subsequent uniform light/light conditions. In order to analyze the circadian rhythm at the genetic level, mutants were induced by N-methyl-N′-nitro-N-nitrosoguanidine and then isolated by procedures with the circadian nitrogen-fixing rhythm as a selecton marker. Characterization of the mutants with respect to the circadian rhythm indicated that some mutants were abnormal only in the nitrogen-fixing rhythm, while some simultaneously lost the ability to establish the nitrogen-fixing and leucine-uptake rhythms. The physiological properties of the circadian rhythm were compared. The genetic potential of the mutants that were abnormal in both rhythms is emphasized.
