Numerical integration of an age-structured population model with infinite life span

作者：

Highlights：

• Age-structured population model with unbounded life span.

• New numerical method which does not truncate the age domain.

• The numerical scheme is completely analyzed and second order of convergence is established.

• Simulation of the correct behaviour of the Nicholson’s blowflies model.
