Pure-injective hulls of modules over valuation rings

If R\hat{R}\otimes\_RMMM$. Moreove…
The CMB temperature power spectrum from an improved analysis of the Archeops data
M. Tristram, G. Patanchon, J. F. Macias-Perez +47
We present improved results on the measurement of the angular power spectrum of the Cosmic Microwave Background (CMB) temperature anisotropies using the data from the last Archeops…
Injective modules and fp-injective modules over valuation rings
Francois Couchot
It is shown that each almost maximal valuation ring R such that every indecomposable injective module is countably generated, satisfies the following condition (C): each fp-injecti…
Modules with RD-composition series over a commutative ring
Francois Couchot
If R is a commutative ring, we prove that every finitely generated module has a pure-composition series with indecomposable factors and any two such series are isomorphic if and on…
The lambda-dimension of commutative arithmetic rings
Francois Couchot
It is shown that every commutative arithmetic ring has -dimension . An example of a commutative Kaplansky ring with -dimension 3 is given. If satis…
RD-flatness and RD-injectivity
Francois Couchot
It is proved that every commutative ring whose RD-injective modules are -RD-injective is the product of a pure semi-simple ring and a finite ring. A complete characterization of…
