Abstract: Recent publications reconsider the growth model proposed by Matsuyama ("Growing through cycles"), also called M-map, presenting new interpretation of the model as well as new results on its dynamic behaviors. The goal of the present paper is to give the rigorous proof of some results which were remaining open, related to the dynamics of this model. We prove that in the whole parameter range of interest an attracting 2-cycle appears via border collision bifurcation, we give the explicit flip bifurcation value of the 2-cycle proving that it is always of subcritical type. This leads to bistability related to coexistence of an attracting 2-cycle with attracting 4-cyclic chaotic intervals. We give the conditions related to the sharp transition to chaos, proving that the cascade of stable cycles of even periods cannot occur. The parameter range in which repelling cycles of odd period exist is further investigated, giving an explicit boundary, as well as its relation to the non existence of cycles of period three. Length: 25 pages
