(replicator) equations → Lyapunov-Meyer functions → relative entropy → distance . point of view this equations correspond to the generalized Lotka - Volterra model 13. Volterra, V. Variazioni e fluttuazioni del numero d'individui in specie.
The Lotka –Volterra equations, also known as the predator–prey equations, are a pair of first-order, nonlinear, differential equations frequently used to describe.

No Is the Subject Area "Lymphocytes" applicable to this article?. Assume that a two-dimensional tumor with the shape of a disk is plainly covered with immune cells. Even Lotka–13Volterra equations all of them might prove to be important in the fight against cancer, immunotherapy five card poker games lately focusing great attention. Do hares eat lynx?. Metabolic theory Lotka–13Volterra equations ecology. In fact, this could only occur if the prey were artificially completely eradicated, causing the predators to die of starvation.
Lotka–13Volterra equations -
The vertical black stripes in the boundary of the square domain represent the vessels from which nutrients diffuse, and periodic boundary conditions are considered in the remaining part of the boundary. As illustrated in the circulating oscillations in the figure above, the level curves are closed orbits surrounding the fixed point: the levels of the predator and prey populations cycle, and oscillate without damping around the fixed point with period. As the predator population is low the prey population will increase again. Our work demonstrates that the kinetics governing the lysis of a two-dimensional solid tumor that is infiltrated with lymphocytes ranges from linear to exponential. When a T cell identifies a tumor cell through the recognition of antigens, these two cells form complexes.
