In 1991 Rowlands proposed an effectively fourth-order, effectively two-stage, explicit symplectic integrator based on using a Hessian–vector product to modify the force evaluation in the leapfrog… (More)

A numerical method for an open marine population model with spaced-limited recruitment is presented. Themethod takes into account the singularity of themortality rate at the finite maximum age, and… (More)

This model describes the evolution with time t of a population structured by its size x. It is determined by the vital functions which include dependencies on both variables and on the total amount… (More)

In this paper, we analyze the convergence of a second-order numerical method for the approximation of a size-structured population model whose dependency on the environment is managed by the… (More)

The proliferative behaviour at the stationary state of a cell population within a tumour cord has been described by a non-classical boundary value problem for a hyperbolic first order integro-partial… (More)
