We use these ingredients to give a constructive definition of next-population-state operators. For the autonomous case we define the basic reproduction ratio R0 and the Malthusian parameter r and we compute the resolvent in terms of the Laplace transform of the ingredients. A key feature of our approach is that unbounded operators are avoided throughout. This will facilitate the treatment of nonlinear models as a next step.</mods:abstract><mods:originInfo><mods:dateIssued encoding="iso8601">1996-06-30</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>CWI</mods:publisher></mods:originInfo><mods:genre>Other</mods:genre></mets:xmlData></mets:mdWrap></mets:dmdSec><mets:amdSec ID="TMD_eprint_4791"><mets:rightsMD ID="rights_eprint_4791_mods"><mets:mdWrap MDTYPE="MODS"><mets:xmlData><mods:useAndReproduction>
