Hilbert Polynomials for the Extension Functor
Let R be a local ring, I ⊆ R an ideal, and M and N finite Rmodules. In this paper we provide a number of results concerning the degree of the polynomial giving the lengths of the modules ExtR(N/I nN, M), when such a polynomial exists. Included among these results are a characterization of when this degree equals the Krull dimension of R, a characterization of when the degree of the polynomial a...
متن کاملHilbert-samuel Polynomials for the Contravariant Extension Functor
Let (R, m) be a local ring and M and N finite R-modules. In this paper we give a formula for the degree of the polynomial giving the lengths of the modules ExtR(M, N/m nN). A number of corollaries are given and more general filtrations are also considered.
متن کاملA Cartesian Closed Extension of the Category of Locales
We present a Cartesian closed category ELoc of equilocales, which contains the category Loc of locales as a reflective full subcategory. The embedding of Loc into ELoc preserves products and all exponentials of exponentiable locales.
متن کاملThe quadratic Fock functor
We construct the quadratic analogue of the boson Fock functor. While in the first order (linear) case all contractions on the 1–particle space can be second quantized, the semigroup of contractions that admit a quadratic second quantization is much smaller due to the nonlinearity. The encouraging fact is that it contains, as proper subgroups (i.e. the contractions), all the gauge transformation...
متن کاملThe Symplectization Functor
We describe a symplectization functor from the Poisson category to the symplectic “category” and we study some of its properties.
