Emergent Directedness in Social Contagion
An enduring challenge in contagion theory is that the pathways contagions follow through social networks exhibit emergent complexities that are difficult to predict using network structure. Here, we address this challenge by developing a causal modeling framework that (i) simulates the possible network pathways that emerge as contagions spread and (ii) identifies which edges and nodes are most impactful on diffusion across these possible pathways. This yields a surprising discovery. If people r…

(E.B. White writes about Hope, to a man who has lost faith in humanity.)
Dear Mr. Nadeau:
As long as there is one upright man, as long as there is one compassionate woman, the contagion may spread and the scene is not desolate. Hope is the thing that is left to us, in a bad time. I shall get up Sunday morning and wind the clock, as a contribution to order and steadfastness.

Burning games on strong path products
Burning and cooling are diffusion processes on graphs in which burned (or cooled) vertices spread to their neighbors with a new source picked at discrete time steps. In burning, the one tries to burn the graph as fast as possible, while in cooling one wants to delay cooling as long as possible. We consider $d$-fold strong products of paths, which generalize king graphs. The propagation of these graphs is radial, and models local spread of contagion in an arbitrary number of dimensions. We red…

Symmetry breaking in collective decision-making through higher-order interactions
Collective decision-making is a widespread phenomenon in both biological and artificial systems, where individuals reach a consensus through social interactions. While traditional models of opinion dynamics and contagion focus on pairwise interactions, recent research emphasizes the importance of including higher-order group interactions and autonomous behavior to better reflect real-world complexity. In this work, we introduce a collective decision-making model inspired by social insects. In o…

Efficient Gillespie algorithms for spreading phenomena in large and heterogeneous higher-order networks
Higher-order dynamics refer to mechanisms where collective mutual or synchronous interactions differ fundamentally from their pairwise counterparts through the concept of many-body interactions. Phenomena absent in pairwise models, such as catastrophic activation, hysteresis, and hybrid transitions, emerge naturally in higher-order interacting systems. Thus, the simulation of contagion dynamics on higher-order structures is algorithmically and computationally challenging due to the complexity o…
