Triadic percolation on multilayer networks arxiv.org/abs/2510.09341
Triadic percolation on multilayer networks
Triadic interactions are special types of higher-order interactions that occur when regulator nodes modulate the interactions between other two or more nodes. In presence of triadic interactions, a pe...
