We interpret the unimodularity condition in almost commutative geometries as central extensions of spin lifts. In Connes’ formulation of the standard model this interpretation allows to compute the… (More)

Two experiments examined the role of the sympathetic nerves in estradiol-induced fat pad weight losses in ovariectomized (OVX) rats. Rats were OVX, and the retroperitoneal white adipose tissue (RWAT)… (More)

Since the appearance of the paper by Bilal et al. in ’91, [1], it has been widely assumed that W–algebras originating from the Hamiltonian reduction of an SL(n,C)-bundle over a Riemann surface give… (More)

The Epstein–Glaser type T -subtraction introduced by one of the authors in a previous paper is extended to the Lorentz invariant framework. The advantage of using our subtraction instead of Epstein… (More)

Starting from flat two-dimensional gauge potentials we propose the notion of W-gauge structure in terms of a nilpotent BRS differential algebra. The decomposition of the underlying Lie algebra with… (More)

Causal perturbative renormalization within the recursive Epstein–Glaser scheme involves extending, at each order, time-ordered operator-valued distributions to coinciding points. This is achieved by… (More)

The purpose of this note is to show that W 3 algebras originate from an unusual interplay between the breakings of the reparametrization invariance under the diffemorphism action on the cotangent… (More)

We study the 1-form diffeomorphism cohomologies within a local conformal Lagrangian Field Theory model built on a two dimensional Riemann surface with no boundary. We consider the case of scalar… (More)

It is proved that general consistency requirements of stability under complex analytic change of charts show that primary currents in finite chiral W-algebras are described in terms of pure… (More)

It is shown how W-algebras emerge from very peculiar canonical transformations with respect to the canonical symplectic structure on a compact Riemann surface. The action of smooth diffeomorphisms of… (More)
