periodic solutions of the volterra's model for the interaction between the biological species.
We first study the volterra's model for k=1 by the liapunov's method.
a family of periodic solutions is obtained in the form of convergent series easly computed in terms of elementary periodic functions, comparison with the results of the numerical integration gives a good coincidence of the two first approximations of the solutions in rather large neighbourhood of the point d'equilibrium....

mathematical models are found in different subdomains of psychology :
- From early beginnings the test and scaling methodology have been important fields in psychology, sophisticated mathematical models have increasngly been used in these fields, we refer to the development of functional probabilistic models and multivariants models, another trend which shows itself in the last years is the development of axiomatic systems.
- The contributions of those psychologists who since the sixties,...
