This paper deals with Rotenberg's models of cell populations with general boundary conditions. It is shown, ΓΏrst, that the associated Cauchy problem is governed by a C 0 -semigroup. Second, we have proved that if the boundary operator is positive, the transport semigroup is irreducible. And ΓΏnally,

This paper deals with the Leibowitz-Rubinow models of population dynamics with general birth laws and zero minimum cycle length. We give generation results in L p -spaces and investigate the spectrum and the asymptotic behavior of the corresponding c 0 -semigroup.
## Abstract In this paper we establish some results regarding the existence of solution on __L__~1~ spaces to a nonlinear boundary value problem originally proposed by Lebowitz and Rubinow (__J. Math. Biol.__ 1974; **1**:17β36) to model an ageβstructured proliferating cell population. Our approach,
