We study the application of a pulse vaccination strategy to eradicate the slowly progressing diseases that have infectiousness in latent period. We derive the condition in which eradication solution i...
EXISTENCE AND UNIQUENESS OF ENDEMIC STATES FOR THE AGE-STRUCTURED SEIR EPIDEMIC MODEL
Age structure positive endemic state S
2007/8/7
An age-structured SEIR epidemic model of a vertically as well as horizontallytransmitted disease is investigated. Threshold results for the existence of endemicstates are established for most cases. U...
In this paper, we derive a lattice model for a single species on infinitepatches of one-dimensional space with that the maturation could occur at any age. Theformulation involves a distribution of pos...
THE OPTIMAL CONTROL OF AGE-DEPENDENT POPULATION DYNAMICS BASED ON PARITY PROGRESSION
Optimal birth number control age-struct
2007/8/7
The optimal control problem for an age-dependent population dynamics basedon parity ratio progression is considered. The functional analytie approach of Dubovitskiiand Milyutin is adopted in the inves...
CRITICAL BIRTH ORDER RATIO CONTROL AND ATTAINABLE SET OF A DISCRETE AGE-DEPENDENT PARITY PSOGRESSION POPULATION SYSTEM
Population dynamics parity progression m
2007/8/7
A colltrolled age-structured difference equation model of population dynamics based on parity progression is discussed. The distribution of the control strategies which guarantee the population to app...
PERIODIC SOLUTIONS AND PERIOD-SIMILARITY OF A GROWTH MODEL WITH AGE-STRUCTURED POPULATION
Age-structured population periodic solut
2007/8/7
The present paper deals with the periodic behaviours of an age-structured population model. The period-similarity is proposed, which reveals a certain similar structure between those population models...
