The “algae blooms” phenomenon – a mathematical model
Pollution with sources from towns and industrial centres affect considerable the ecosystem waters. An accumulation of nutrients favourable to the growth of certain tiny marine organisms called phytoplankton stimulates their rapid reproduction in the water. These plankton blooms appear as patches on the surface of the water. The consequence of this process is the diminishing of the amount of oxygen from water (in the process of decompose the algae),

Read moreDegenerated Hopf bifurcation in a mathematical model of economical dynamics
It is assumed that the dynamics of the capital of a firm is governed by a Cauchy problem for a system of two nonlinear ordinary differential equations containing three real parameters. In this paper we determine a k > 3 order degenerated Hopf bifurcation point for this economical model. To this aim the normal form technique is used.

Read moreThe strategies for monetary policy
Generally, the activities are more complexes, the need to planning, to search strategies and formal and systemic actions grow. In monetary domain the grade of incertitude and of risk is very high and the planning plays an important role for reduce these. Essentially, the elaboration for strategies in this domain means a clear and systematic pattern for the ways with the help of the followed target can be realized with a wise assigning for the resources
Read moreA software tool for study stability and equilibrium on financial derivates market
The stability and equilibrium of the stock market system constitutes a permanent preoccupation of the management system. The stock market manager is interested in obtaining certain stability and a real equilibrium of the market which he organizes in the purpose of making transactions with financial assets. Starting from this idea, in this paragraph we want to model the activity of the stock market system with the help of certain general models of
