Extreme values of the resurgence for homogeneous ideals in polynomial rings
نویسندگان
چکیده
We show that two ostensibly different versions of the asymptotic resurgence introduced by E. Guardo, B. Harbourne and A. Van Tuyl in 2013 are same. also attain their maximal values simultaneously, if at all, which we apply to a conjecture Grifo. For radical ideals points, minimal simultaneously. In addition, introduce an integral closure version relate it other resurgence. closing provide various examples raise some related questions, finish with remarks about computing

On annihilator ideals in skew polynomial rings
This article examines annihilators in the skew polynomial ring $R[x;alpha,delta]$. A ring is strongly right $AB$ if everynon-zero right annihilator is bounded. In this paper, we introduce and investigate a particular class of McCoy rings which satisfy Property ($A$) and the conditions asked by P.P. Nielsen. We assume that $R$ is an ($alpha$,$delta$)-compatible ring, and prove that, if $R$ is ni...
متن کاملA Property of Ideals in Polynomial Rings
Every ideal in the polynomial ring in n variables over an infinite field has a reduction generated by n elements. Eisenbud and Evans [2] proved that every ideal in k[Xx,...,Xn] can be generated up to radical by n elements (where k is a field). Avinash Sathaye [7] and Mohan Kumar [5] proved a locally complete intersection in k[ Xv ..., Xn] can be generated by n elements. In this short note we sh...
متن کاملAssociated Prime Ideals of Skew Polynomial Rings
In this paper, it has been proved that for a Noetherian ring R and an automorphism σ of R, an associated prime ideal of R[x, σ] or R[x, x−1, σ] is the extension of its contraction to R and this contraction is the intersection of the orbit under σ of some associated prime ideal of R. The same statement is true for minimal prime ideals also. It has also been proved that for a Noetherian Q-algebra...
متن کاملOn primitive ideals in polynomial rings over nil rings
Let R be a nil ring. We prove that primitive ideals in the polynomial ring R[x] in one indeterminate over R are of the form I [x] for some ideals I of R. All considered rings are associative but not necessarily have identities. Köthe’s conjecture states that a ring without nil ideals has no one-sided nil ideals. It is equivalent [4] to the assertion that polynomial rings over nil rings are Jaco...
متن کاملMinimal Generators for Invariant Ideals in Infinite Dimensional Polynomial Rings
Let K be a field, and let R = K[X] be the polynomial ring in an infinite collection X of indeterminates over K. Let SX be the symmetric group of X. The group SX acts naturally on R, and this in turn gives R the structure of a left module over the group ring R[SX ]. A recent theorem of Aschenbrenner and Hillar states that the module R is Noetherian. We address whether submodules of R can have an...
