چکیده

A Noetherian local ring ( R , m mathvariant="fraktur" stretchy="false">) (R,\frak {m}) is called Buchsbaum if the difference alttext="script l left-parenthesis slash q right-parenthesis minus e ? / mathvariant="fraktur">q ? e encoding="application/x-tex">\ell (R/\mathfrak {q})-e(\mathfrak {q}, R) , where alttext="German q"> encoding="application/x-tex">\mathfrak {q} an ideal generated by a system of parameters, constant independent . In this article, we study tight closure analog condition. We prove that in unmixed excellent prime characteristic alttext="p greater-than 0"> p &gt; 0 encoding="application/x-tex">p&gt;0 and dimension at least one, alttext="e script Superscript asterisk Baseline ?<!-- ? </mml:msup> encoding="application/x-tex">e(\mathfrak R)-\ell {q}^*) only parameter test alttext="tau Subscript normal p r ?<!-- ? mathvariant="normal">p mathvariant="normal">a mathvariant="normal">r encoding="application/x-tex">\tau _{\mathrm {par}}(R) contains m"> encoding="application/x-tex">\frak {m} also provide characterization condition via derived category which analogous to Schenzel’s criterion for rings.

Generic Bounds for Frobenius Closure and Tight Closure

We use geometric and cohomological methods to show that given a degree bound for membership in ideals of a fixed degree type in the polynomial ring P = k[x1, . . . , xd], one obtains a good generic degree bound for membership in the tight closure of an ideal of that degree type in any standard-graded k-algebra R of dimension d. This indicates that the tight closure of an ideal behaves more unif...

Tight Closure and plus Closure for Cones over Elliptic Curves

We characterize the tight closure of graded primary ideals in a homogeneous coordinate ring over an elliptic curve by numerical conditions and we show that it is in positive characteristic the same as the plus closure.

Relative test elements for tight closure

Test ideals play a crucial role in the theory of tight closure developed by Melvin Hochster and Craig Huneke. Recently, Karen Smith showed that test ideals are closely related to certain multiplier ideals that arise in vanishing theorems in algebraic geometry. In this paper we develop a generalization of the notion of test ideals: for complete local rings R and S, where S is a module-6nite exte...

Localization and Test Exponents for Tight Closure

We introduce the notion of a test exponent for tight closure, and explore its relationship with the problem of showing that tight closure commutes with localization, a longstanding open question. Roughly speaking, test exponents exist if and only if tight closure commutes with localization: mild conditions on the ring are needed to prove this. We give other, independent, conditions that are nec...

Tight Closure and Differential Simplicity

The behavior of the Hasse–Schmidt algebra under étale extension is used to show that the Hasse–Schmidt algebra of a smooth algebra of finite type over a field equals the ring of differential operators. These techniques show that the formation of Hasse–Schmidt derivations does not commute with localization, providing a counterexample to a question of Brown and Kuan; their conjecture is reformula...
