A coupled cell network represents dynamical systems (the coupled cell systems) that can be seen as a set of individual dynamical systems (the cells) with interactions between them. Every coupled cell system associated to a network, when restricted to a flow-invariant subspace defined by the equality of certain cell coordinates, corresponds to a coupled cell system associated to a smaller networ...

INTRODUCTION The relationship between developmental and mental deficits due to genetic or acquired causes is well established. However the possible relationship between neurological signs and intellectual development has not been sufficiently studied. OBJECTIVE We have conducted a transversal study to test the possible association between neurological signs and psychometric measures in childr...

We report on an investigation of four-dimensional terminal cyclic quotient singularities which are not Gorenstein. (For simplicity, we focus on quotients by cyclic groups of prime order.) An enumeration, using a computer, of all such singularities for primes < 1600 led us to conjecture a structure theorem for these singularities (which is rather more complicated than the known structure theorem...

In the theory of algebraic group actions on affine varieties, the concept of a Kempf–Ness set is used to replace the geometric quotient by the quotient with respect to a maximal compact subgroup. By making use of the recent achievements of “toric topology” we show that an appropriate notion of a Kempf–Ness set exists for a class of algebraic torus actions on quasiaffine varieties (coordinate su...

Symmetry reduction is a technique to alleviate state explosion in model checking by replacing a model of replicated processes with a bisimilar quotient model. The size of the quotient depends strongly on the set of applicable symmetries, which in many practical cases allows only polynomial reduction. We introduce architectural symmetry, a concept that exploits architectural system features to c...

We study partially hyperbolic diffeomorphisms satisfying a trapping property which makes them look as if they were Anosov at large scale. We show that, as expected, they share several properties with Anosov diffeomorphisms. We construct an expansive quotient of the dynamics and study some dynamical consequences related to this quotient.

We consider the Euler system describing a one-dimensional inviscid flows in space along curves of certain class. Using differential invariants for system, we obtain its quotient equation. The solutions equation that are constant characteristic vector field provide some system. discuss solving using asymptotic expansions unknown functions and virial expansion thermodynamic state equations. Thus ...
