On Separable Abelian Extensions of Rings
Let R be a ring with I, G (= (1>x...Xm) a finite abelian automorphism group of R of order n where (i2 is cyclic of order n. for some integers n, hi, and m, and C the center of R whose automorphism group induced by G is isomorphic with G. Then an abelian extension Rtx 1,...,xm is defined as a generalization of cyclic extensions of rings, and RXl,...,Xm is an Azumaya algebra over K (= CG {c in C ...
متن کاملConstruction of Invariant Non-separable Extensions of the Measure Defined by H-valued Measurable G-process on H
For an arbitrary infinite additive group G and for an uncountable compact Hausdorff topological group H with card(H) = card(Hא0) = card(H), H-valued measurable Gprocesses are constructed on the group H and some set-theoretical characteristics of their various F∗(HG)-invariant extensions are calculated, where F∗(HG) denotes a group of transformations of H generated by the eventually neutral sequ...

15 صفحه اولSeparable integral extensions and plus closure
We show that an excellent local domain of characteristic p has a separable big Cohen–Macaulay algebra. In the course of our work we prove that an element which is in the Frobenius closure of an ideal can be forced into the expansion of the ideal to a module-finite separable extension ring.
متن کاملTrihamiltonian extensions of separable systems in the plane
A method to construct trihamiltonian extensions of a separable system is presented. The procedure is tested for systems, with a natural Hamiltonian, separable in classical sense in one of the four orthogonal separable coordinate systems of the Euclidean plane, and some explicit examples are constructed. Finally a conjecture on possible generalizations to other classes of systems is discussed: i...
