Positive equilibrium values varying γ. The coordinates of the positive equilibrium points varying γ. In (a) we show the coordinates of the small equilibrium point , and in (b), of the big equilibrium point . In (b) we also show the curve of T
, which is always greater than T>. The small root T<decreases, while the big one T> decreases after an initial increase. The scales of vertical and horizontal axes must be multiplied by the factors shown in the legends to obtain the actual values.
