Abstract
We use p-adic numbers to describe a model with limited growth of population (see, for example, [1] and the first section of this paper for p-adic numbers). Dynamics of growth is described by the well-known logistic differential equation:
where N(t) is a population number at the moment t, k = k + - k - is a coefficient of growth. The solution of the equation (1) is the map:
Using p-adic analysis (integration with respect to a Haar measure with p-adic values), we get a representation of the solution (2) as a mixture of maps: nij(t) = e jkt , j = 1, 2,… These maps are the solutions of the equation:
with α = jk. They describe the dynamics of population for a model with unlimited growth.
