The homotopy type of toric arrangements
Luca Moci, Simona Settepanella
A toric arrangement is a finite set of hypersurfaces in a complex torus, every hypersurface being the kernel of a character. In the present paper we build a CW-complex homotopy equ…
Complex Networks and Symmetry II: Reciprocity and Evolution of World Trade
Franco Ruzzenenti, Diego Garlaschelli, Riccardo Basosi
We exploit the symmetry concepts developed in the companion review of this article to introduce a stochastic version of link reversal symmetry, which leads to an improved understan…
Identifying the Community Structure of the International-Trade Multi Network
Matteo Barigozzi, Giorgio Fagiolo, Giuseppe Mangioni
We study the community structure of the multi-network of commodity-specific trade relations among world countries over the 1992-2003 period. We compare structures across commoditie…
The integer cohomology of toric Weyl arrangements
Simona Settepanella
A referee found an error in the proof of the Theorem 2 that we could not fix. More precisely, the proof of Lemma 2.1 is incorrect. Hence the fact that integer cohomology of complem…
Complex Networks and Symmetry I: A Review
Diego Garlaschelli, Franco Ruzzenenti, Riccardo Basosi
In this review we establish various connections between complex networks and symmetry. While special types of symmetries (e.g., automorphisms) are studied in detail within discrete…
Modularity and Optimality in Social Choice
Gennaro Amendola, Simona Settepanella
Marengo and the second author have developed in the last years a geometric model of social choice when this takes place among bundles of interdependent elements, showing that by bu…
