Stratification of the orbit space in gauge theories. The role of nongeneric strata

R. Vilela Mendes

Gauge theory is a theory with constraints and, for that reason, the space of physical states is not a manifold but a stratified space (orbifold) with singularities. The classificat…

Reconstructing an economic space from a market metric

R. Vilela Mendes, Tanya Araújo, Francisco Louçã

Using a metric related to the returns correlation, a method is proposed to reconstruct an economic space from the market data. A reduced subspace, associated to the systematic stru…

Quantum sensitive dependence

V. I. Man'ko, R. Vilela Mendes

Wave functions of bounded quantum systems with time-independent potentials, being almost periodic functions, cannot have time asymptotics as in classical chaos. However, bounded qu…

A dynamical characterization of the small world phase

Tanya Araujo, R. Vilela Mendes, João Seixas

Small-world (SW) networks have been identified in many different fields. Topological coefficients like the clustering coefficient and the characteristic path length have been used…
