We identify the kinks of a deformed O(3) linear Sigma model as the solutionsof a set of first-order systems of equations; the above model is ageneralization of the MSTB model with a three-component scalar field. Takinginto account certain kink energy sum rules we show that the variety of kinkshas the structure of a moduli space that can be compactified in a fairlynatural way. The generic kinks, however, are unstable and Morse Theory providesthe framework for the analysis of kink stability.Comment: 32 pages, 1 figure; to appear in Nonlinearit
