We consider free superconformal theories of N = 8 scalar multiplet in d = 3 and (2, 0) tensor multiplet in d = 6 and compute 2-point and 3-point correlators of their stress tensors. The results for the 2-point and the 3-point correlators for a single d = 3 and d = 6 multiplet differ from the “strong-coupling” AdS4 and AdS7 supergravity predictions by the… (More)

50 undergraduates were tested on a mental synthesis task aimed at producing creative visual patterns and were administered three questionnaires measuring imagery vividness and control. Analysis did not support a relationship between scores on visual synthesis and imagery and showed that neither kind of score was influenced by sex and studies attended.

We show that the global aspects of Abelian and center projection of a SU(2) gauge theory on an arbitrary manifold are naturally described in terms of smooth Deligne cohomology. This is achieved through the introduction of a novel type of differential topological structure, called Cho structure. Half integral monopole charges appear naturally in this… (More)

The aim of this work is to put forward a statistical mechanics theory of social interaction, generalizing econometric discrete choice models. After showing the formal equivalence linking econometric multinomial logit models to equilibrium statical mechanics, a multi-population generalization of the Curie-Weiss model for ferromagnets is considered as a… (More)

A program to compute the Birkhoo normal forms for symplectic maps in l R 4 is described. We consider the case of an elliptic xed point, which is the most relevant for applications. We compute the normal forms both in the nonresonant and resonant case and we provide the interpolating hamiltonian and the normalizing transformation. Programming language:… (More)

From observations of almost 500 RGB stars in 29 Galactic open and globular clusters, we have investigated the behaviour of the infrared Ca II triplet (8498, 8542 and 8662 Å) in the age range 13≤Age/Gyr≤0.25 and the metallicity range −2.2 ≤ [Fe/H] ≤+0.47. These are the widest ranges of ages and metallicities in which the behaviour of the Ca II triplet lines… (More)
