Graph-Induced Tensor Liftings for Networked SEIR Models: Dimensional Reduction and Residual Analysis
Networked SEIR models describe epidemic spread within and between interacting subpopulations through contact-supported nonlinear transmission. Standard polynomial liftings based on complete ordered Kronecker tensors yield linear higher-dimensional representations, but their dimen…
