Multilinear forms which are products of linear forms
The conditions under which, multilinear forms (the symmetric case and the non symmetric case),can be written as a product of linear forms, are considered. Also we generalize a result due to S.Kurepa for 2n-functionals in a group G.
متن کاملModules for which every non-cosingular submodule is a summand
A module $M$ is lifting if and only if $M$ is amply supplemented and every coclosed submodule of $M$ is a direct summand. In this paper, we are interested in a generalization of lifting modules by removing the condition"amply supplemented" and just focus on modules such that every non-cosingular submodule of them is a summand. We call these modules NS. We investigate some gen...

متن کاملClifford Modules and Invariants of Quadratic Forms
We construct new invariants of quadratic forms over commutative rings, using ideas from Topology. More precisely, we de ne a hermitian analog of the Bott class with target algebraic K-theory, based on the classi cation of Cli¤ord modules. These invariants of quadratic forms go beyond the classical invariants de ned via the Cli¤ord algebra. An appendix by J.-P. Serre, of independent interest, de...
متن کاملON THE PERMUTATION MODULES FOR ORTHOGONAL GROUPS O± m(3) ACTING ON NONSINGULAR POINTS OF THEIR STANDARD MODULES
We describe the structure, including composition factors and submodule lattices, of cross-characteristic permutation modules for the natural actions of the orthogonal groups O± m(3) with m ≥ 6 on nonsingular points of their standard modules. These actions together with those studied in [2] are all examples of primitive rank 3 actions of finite classical groups on nonsingular points.
