The interaction among spreading processes on a complex network is a nontrivial
phenomenon of great importance. It has recently been realized that cooperative effects …

A simple model to study cooperation is the two-species symbiotic contact process (2SCP), in
which two different species spread on a graph and interact by a reduced death rate if both …

In many real-world contagion phenomena, the number of contacts to spreading entities for
adoption varies for different individuals. Therefore, we study a model of contagion dynamics …

We investigate mixed-order critical phenomena of the generalized epidemic process (GEP)
on random scale-free networks characterized by the power-law distribution pk∼ k− α. The …
