摘要:
We study the automorphisrn group of MDS codes which are invariant under a doubly transitive group, and we apply this result to the affine-invariant codes. Using the description of codes into a modular algebra, we characterize the affine-invariant codes which are equivalent to Reed-Solomon codes, then we construct an affine-invariant MDS code which is not equivalent to Reed-Solomon codes.

摘要:
We study various features of the lattice LMof linear module topologies on a module M and their impact on the structure of the abstract module. A particular emphasis is given to: a) permanence properties of 1- minimal topologies (=atoms in the subset of LMof Hausdorff topologies) in analogy with the theory of minimal topological groups; b) the usual equivalence between linear topologies and the equivalence classes of the atoms; c) characterization of the abstract modules M such that certain classes in LMare singletons (in particular, modules such that each non-discrete linear topology is topologically artinian). Point c) involves the class of modules having all proper quotients artinian.

摘要:
It is proved consistent with either CH ⌝CHor that there is an separable group of cardinality which does not have a coherent system of projections.It had previously been shown that it is consistent with ⌝CH that everyN1-separable group of cardinalityN1does have a coherent system of projections.
