Positive global solutions for a general model of size-dependent population dynamics

Nobuyuki Kato

Abstract and Applied Analysis, 2000, vol. 5, 1-16

Abstract:

We study size-structured population models of general type which have the growth rate depending on the size and time. The local existence and uniqueness of the solution have been shown by Kato and Torikata (1997). Here, we discuss the positivity of the solution and global existence as well as L   ∞ solutions.
