The (pseudo)issue of the conformal frame revisited
Valerio Faraoni, Shahn Nadeau
The issue of the equivalence between Jordan and Einstein conformal frames in scalar-tensor gravity is revisited, with emphasis on implementing running units in the latter. The lack…
Matter instability in modified gravity
Valerio Faraoni
The Dolgov-Kawasaki instability discovered in the matter sector of the modified gravity scenario incorporating a 1/R correction to Einstein gravity is studied in general f(R) theor…
Casimir piston for massless scalar fields in three dimensions
Ariel Edery
We study the Casimir piston for massless scalar fields obeying Dirichlet boundary conditions in a three dimensional cavity with sides of arbitrary lengths and where i…
-cluster categories and -replicated algebras
I. Assem, T. Brüstle, R. Schiffler +1
Let A be a hereditary algebra over an algebraically closed field. We prove that an exact fundamental domain for the m-cluster category of A is the m-left part of the m-replicated a…
(Co)Homology theories for oriented algebras
Juan Carlos Bustamante, Julie Dionne, David Smith
We study three different (co)homology theories for a family of pullbacks of algebras that we call oriented. We obtain a Mayer Vietoris long exact sequence of Hochschild and cyclic…
Spontaneous breaking of conformal invariance in theories of conformally coupled matter and Weyl gravity
A. Edery, Luca Fabbri, M. B. Paranjape
We study the theory of Weyl conformal gravity with matter degrees of freedom in a conformally invariant interaction. Specifically, we consider a triplet of scalar fields and SO(3)…
