Table 1 Number and stability of endemic equilibria
From: Bifurcations of an SIRS model with generalized non-monotone incidence rate
p | Condition | Number | Stability |
|---|---|---|---|
p<1 | d>0 | 1 | globally stable |
p = 1 | d<A | 1 | globally stable |
d ≥ A | 0 | ||
p>1 | \(d< d_{m}\) | 2 | a saddle and an anti-saddle |
\(d=d_{m}\) | 1 | degenerate sigularity | |
\(d>d_{m}\) | 0 |
