In the present paper a nonlinear size-structured population dynamical model with size and
density dependent vital rate functions is considered. The linearization about stationary …

We consider a population organised hierarchically with respect to size in such a way that the
growth rate of each individual depends only on the presence of larger individuals. As a …

We employ semigroup and spectral methods to analyze the linear stability of positive
stationary solutions of a generalized size-structured Daphnia model. Using the regularity …

This paper generalizes a class of controllability problems based on the scale structure
population system model. Based on the comparison principle of linear systems, the solution …

In this work, first, we consider a physiologically structured population model with a
distributed recruitment process. That is, our model allows newly recruited individuals to enter …

In this work a size structured juvenile-adult population model is considered. The linearized
dynamical behavior of stationary solutions is analyzed using semigroup and spectral …

In this paper we develop a high order explicit finite difference weighted essentially non-
oscillatory (WENO) scheme for solving a hierarchical size-structured population model with …

This article is concerned with theoretic analysis and numerical approximation of solutions to
a hierarchical age-structured population model, in which the vital rates of an individual …

In this paper we present a proof of existence and uniqueness of solution for a class of PDE
models of size structured populations with distributed state-at-birth and having nonlinearities …

In this paper we investigate a structured population model with distributed delay. Our model
incorporates two different types of nonlinearities. Specifically we assume that individual …
