Letpbe an odd prime and k <p. This paper gives a classification of vertex primitive symmetric graphs of orderkp, where k is not a prime. This paper and [16] together give a complete classification of all vertex primitive symmetric graphs of orderkp.

摘要:

We generalize classical results of tranfer properties to finite intersections of pullbacks at various maximal ideals of a domain T; we also get new transfer results on the dimension formula.

摘要:

Several different constructions of a structure sheaf over noetherian noncommutative rings have been made in the recent past; however the problem of functoriality remains open in the general case. Here we present a new approach to the problem. Since the two-sided structure of the ring is fundamental in finding a solution of the above problem it seems natural to evaluate the sheaf functors on (normalizing) bimod-ules. In this context, biradicals arise as a useful tool as well as classical localization at prime ideals and cliques. The main results are valid for noetherian rings satisfying the strong second layer condition in which every clique is classically localizable. This paper can be considered an extension of [5], and develops its results outside of FBN rings.

摘要:

Suppose (R,m) →(S,n) is a local homomorphism of lo­cal rings. We show that if M is a Matlis reflexive R-module, thenR(S,M) and TorR(S,M) are Matlis reflexive S-modules if S is module-finite over the image of R. In case S = [Rcirc], the m-adic comple­tion of A, we show that ifMis a reflexive R-module, then [Rcirc] ⊗RMis a reflexive [Rcirc]-module and in factWe also show that if R is any local ring andMandNare two reflexive Ä-modules, then ExtR(M,N) and TorR(M,N) are reflexiveR-modules for all i.

摘要:

A finite basis of identities is constructed for the semigroup of all rank 1 n × n matri­ces over the field. It is worthy to notice that every semigroup of all rank r, r > l,n×n matrices over a finite field has no finite basis of identities. Let G be an arbitrary vari­ety of groups with a finite basis of identities. A finite basis of identities is constructed for the variety generated by all completely 0-simple semigroups over G-groups.

摘要:

The 5-modular decomposition numbers of the two simple Fischer groups Fi22and Fi23and also those of the two maximal subgroups2. Fi22andof Fi23are determined. In an appendix Thomas Breuer comments on his construction of the ordinary character tables of the groups, which occur as maximal subgroups of 2. Fi22respectively Fi23- The results were obtained with the help of the computer algebra systems MOC [4] and GAP [10].
