-deformations of graded rings
Alessandro Ardizzoni, Paolo Saracco, Dragoş Ştefan
We prove in a very general framework several versions of the classical Poincaré-Birkhoff-Witt Theorem, which extend results from [BeGi, BrGa, CS, HvOZ, WW]. Applications and exampl…
Comparing topologies on linearly recursive sequences
Laiachi El Kaoutit, Paolo Saracco
The space of linearly recursive sequences of complex numbers admits two distinguished topologies. Namely, the adic topology induced by the ideal of those sequences whose first term…
Topological tensor product of bimodules, complete Hopf Algebroids and convolution algebras
Laiachi El Kaoutit, Paolo Saracco
Given a finitely generated and projective Lie-Rinehart algebra, we show that there is a continuous homomorphism of complete commutative Hopf algebroids between the completion of th…
Colour gradients in cluster ellipticals at z~1.4: the hidden content of the galaxy central regions
Federica Ciocca, Paolo Saracco, Adriana Gargiulo +1
We present F775W-F850LP (rest-frame UV-U) and F850LP-F160W (rest-frame U-R) colour gradients for a sample of 17 elliptical galaxies morphologically selected in the cluster XMMU J22…
