Characteristic multipliers for some periodic differential equations. [PDF]

open access: yesProceedings of the American Mathematical Society, 1969
Calculation of the characteristic multipliers is not routine since in general one does not know even one nontrivial solution of (1). However it is possible to obtain convergent series representations for the solutions and thus calculate approximate values for the multipliers [2], [8].
