Variational characterizations of weighted eigenvalue and basic reproduction ratio for nonlocal dispersal systems and application
Xiandong Lin, Jiazhuo Cheng, Qiru Wang
The basic reproduction ratio is a crucial threshold parameter in infectious disease models. In nonlocal dispersal systems, its variational characterization is challenging due to th…
