Nonautonomous ultraparabolic equations applied to population dynamics
Electronic journal of differential equations, Tome 2005 (2005)
We prove the existence and positivity of solutions to nonautonomus ultraparabolic equations using a perturbation method. These equations come from population dynamics, namely from a fish larvae model.
Classification : 35G10, 35K70
Keywords: ultraparabolic equations, perturbation, dynamics of the fish larvae
