We consider a linear size-structured population model with diffusion in the size-space.
Individuals are recruited into the population at arbitrary sizes. The model is equipped with …

We introduce a non-linear structured population model with diffusion in the state space.
Individuals are structured with respect to a continuous variable which represents a pathogen …

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 …

First-order hyperbolic partial differential equations with two internal variables have been
used to model biological and epidemiological problems with two physiological structures …

In this paper we consider a physiologically structured population model with distributed
states at birth, formulated on the space of non-negative Radon measures. Using a …

In this paper we explore the eco-evolutionary dynamics of a predator-prey model, where the
prey population is structured according to a certain life history trait. The trait distribution …

In this paper, we study a size-structured population model with infinite states-at-birth and
distributed delay in birth process. We are interested in the asymptotic behavior of the …

We investigate steady states of a quasilinear first order hyperbolic partial integro-differential
equation. The model describes the evolution of a hierarchical structured population with …

We study the question of existence of positive steady states of nonlinear evolution
equations. We recast the steady state equation in the form of eigenvalue problems for a …

In this paper we study the two-phase size-structured population model with infinite states-at-
birth and distributed delay in birth process. The model distinguishes individuals by two …
