Abstract:
In this paper we propose to analyze the growth of scientific
results in terms of infinite dynamical system theory.
We use functional differential equations to model evolution
of science in the sociological aspect. In our model
time-to-build of scientific notions (understanding) is
included. It is a similar concept to the Levy-Blond recasting
process. We show that the delay parameter describing time needed
to learn and apply the past scientific results to new discoveries
plays a crucial role in generating the cyclic behaviour via
the Hopf bifurcation scenario. Our model extends the de Sola Price
model by including dying of results as well as by incorporating
time-to-build notion.
