Q–gorenstein Splinter Rings of Characteristic P Are F–regular
A Noetherian integral domain R is said to be a splinter if it is a direct summand, as an R–module, of every module–finite extension ring, see [Ma]. In the case that R contains the field of rational numbers, it is easily seen that R is splinter if and only if it is a normal ring, but the notion is more subtle for rings of characteristic p > 0. It is known that F–regular rings of characteristic p...
متن کاملGorenstein rings through face rings of manifolds
The face ring of a homology manifold (without boundary) modulo a generic system of parameters is studied. Its socle is computed and it is verified that a particular quotient of this ring is Gorenstein. This fact is used to prove that the sphere g-conjecture implies all enumerative consequences of its far reaching generalization (due to Kalai) to manifolds. A special case of Kalai’s manifold g-c...
متن کاملOBSERVATIONS ON THE F -SIGNATURE OF LOCAL RINGS OF CHARACTERISTIC p
Let (R,m, k) be a d-dimensional Noetherian reduced local ring of prime characteristic p such that R1/p e are finite over R for all e ∈ N (i.e. R is F -finite). Consider the sequence { ae qα(R)+d }e=0, in which α(R) = logp[k : kp], q = pe, and ae is the maximal rank of free R-modules appearing as direct summands of R-module R1/q . Denote by s−(R) and s+(R) the liminf and limsup respectively of t...
متن کاملOn Some Characteristic Properties of Quasi-frobenius and Regular Rings
Recently the first writer [l] gave a characterization of quasiFrobenius rings, introduced formerly by the second writer [3], in terms of a condition proposed by K. Shoda, which reads: A ring A satisfying minimum condition and possessing a unit element is a quasi-Frobenius ring if and only if A satisfies the following condition:1 (a) every (A -left-) homomorphism of a left-ideal of A into A may ...
متن کاملRelative (co)homology of $F$-Gorenstein modules
We investigate the relative cohomology and relative homology theories of $F$-Gorenstein modules, consider the relations between classical and $F$-Gorenstein (co)homology theories.
