Threshold Dynamics, Endemic Stability, and Degree-Targeted Optimal Control of HIV/AIDS on Heterogeneous Contact Networks
Contact heterogeneity can substantially alter HIV/AIDS transmission thresholds and intervention efficiency, yet many control models retain homogeneous mixing. We develop a conservative degree-structured susceptible–infectious–removed model on correlated contact networks with demographic replacement. Positivity, forward...
