Envelopes of commutative rings

Rafael Parra, Manuel Saorin

Given a significative class of commutative rings, we study the precise conditions under which a commutative ring has an -envelope. A full answer is obtained when is…

On the scalar curvature of hypersurfaces in spaces with a Killing field

Alma L. Albujer, Juan A. Aledo, Luis J. Alias

We consider compact hypersurfaces in an -dimensional either Riemannian or Lorentzian space endowed with a conformal Killing vector field. For such hypersurfaces, w…

On the ϕ(1020)f_0(980) S-wave scattering and the Y(2175) resonance

L. Alvarez-Ruso, J. A. Oller, J. M. Alarcon

We have studied the ϕ(1020)f_0(980) S-wave scattering at energies around threshold employing chiral Lagrangians coupled to vector mesons through minimal coupling. The interaction k…

Boolean metric spaces and Boolean algebraic varieties

Antonio Avilés

The concepts of Boolean metric space and convex combination are used to characterize polynomial maps in a class of commutative Von Neumann regular rings including Boolean rings and…

Commutative rings with finite quotient fields

Antonio Avilés

We consider the class of all commutative reduced rings for which there exists a finite subset T of A such that all projections on quotients by prime ideals of A are surjective when…

Renormings of the dual of James tree spaces

Antonio Avilés

We discuss renorming properties of the dual of a James tree space JT. We present examples of weakly Lindelof determined JT such that JT* admits neither strictly convex nor Kadec re…
