Hopf bifurcation in a dynamic IS-LM model with time delay
Mihaela Neamtu, Dumitru Opris, Constantin Chilarescu
In this paper we investigate the impact of delayed tax revenues on the fiscal policy out-comes. Choosing the delay as a bifurcation parameter we study the direction and the stabili…
Dynamical Systems on Leibniz Algebroids
G. Ivan, D. Opris
In this paper we study the differential systems on Leibniz algebroids. We introduce a class of almost metriplectic manifolds as a special case of Leibniz manifolds. Also, the notio…
Leibniz Dynamics with Time Delay
I. D. Albu, D. Opris
In this paper we show that several dynamical systems with time delay can be described as vector fields associated to smooth functions via a bracket of Leibniz structure. Some examp…
A Dynamic P53-MDM2 Model with Time Delay
Gh. I. Mihalas, M. Neamtu, D. Opris +1
Specific activator and repressor transcription factors which bind to specific regulator DNA sequences, play an important role in gene activity control. Interactions between genes c…
