Age-Structured Epidemic

Leslie matrix demographics + SIR compartmental dynamics by age group

Disease Parameters

Leslie Matrix

n(t+1) = L · n(t)

L = [ f₁ f₂ ... fₙ ]
[ s₁ 0 ... 0 ]
[ 0 s₂ ... 0 ]
[ 0 0 ... sₙ₋₁]

fᵢ = age-specific fertility
sᵢ = survival probability

λ₁ = dominant eigenvalue
= asymptotic growth rate
