DOI: 10.1080/00036811.2017.1408075
Abstract: ABSTRACT 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 considered system and, particularly, in the effect… read more here.

DOI: 10.3390/math11102393
Abstract: Maturation strategies play a key role in the survival and development of populations. In response to changes in the external environment and human interventions, populations adopt appropriate maturation strategies. Different maturation strategies can lead to… read more here.
