Logistic and -logistic models in population dynamics: General analysis and exact results
Nicola Cufaro Petroni, Salvatore De Martino, Silvio De Siena
In the present paper we provide the closed form of the path-like solutions for the logistic and -logistic stochastic differential equations, along with the exact expressions of…
Stochastic origin of Gompertzian growths
E. De Lauro, S. De Martino, S. De Siena +1
This work faces the problem of the origin of the logarithmic character of the Gompertzian growth. We show that the macroscopic, deterministic Gompertz equation describes the evolut…
Hierarchical Gompertzian growth maps with application in astrophysics
S. De Martino, S. De Siena
The Gompertz model describes the growth in time of the size of significant quantities associated to a large number of systems, taking into account nonlinearity features by a linear…
Hydrodynamic covariant symplectic structure from bilinear Hamiltonian functions
S. Capozziello, S. De Martino, S. I. Tzenov
Starting from generic bilinear Hamiltonians, constructed by covariant vector, bivector or tensor fields, it is possible to derive a general symplectic structure which leads to holo…
Whistleron Gas in Magnetized Plasmas
Salvatore De Martino, Mariarosaria Falanga, Stephan I. Tzenov
We have studied the nonlinear dynamics of whistler waves in magnetized plasmas. Since plasmas and beam-plasma systems considered here are assumed to be weakly collisional, the poin…
Constraining Van der Waals quintessence by observations
S. Capozziello, V. F. Cardone, S. Carloni +4
We discuss an alternative approach to quintessence modifying the usual equation of state of the cosmological fluid in order to see if going further than the approximation of perfec…
