We apply the method of parametrized continued fractions to the solution of systems of linear algebraic equations on the basis of their Liouville–Neumann formal power series. We construct an analog of the Cramer formula, which is also applicable to the cases of singular, ill-posed, and rectangular matrices. 相似文献

The goal of this paper is to generalize a theorem of Fujiwara (Deligne’s conjecture) to the situation appearing in a joint
work [KV] with David Kazhdan on the global Langlands correspondence over function fields. Moreover, our proof is more elementary
than the original one and stays in the realm of ordinary algebraic geometry, that is, does not use rigid geometry. We also
give a proof of the Lefschetz–Verdier trace formula and of the additivity of filtered trace maps, thus making the paper essentially
self-contained.

Abstract A ring R is called left IP-injective if every homomorphism from a left ideal of R into R with principal image is given by right multiplication by an element of R. It is shown that R is left IP-injective if and only if R is left P-injective and left GIN (i.e., r(I ∩ K) = r(I) + r(K) for each pair of left ideals I and K of R with I principal). We prove that R is QF if and only if R is right noetherian and left IP-injective if and only if R is left perfect, left GIN and right simple-injective. We also show that, for a right CF left GIN-ring R, R is QF if and only if Soc(R R ) ? Soc( R R). Two examples are given to show that an IP-injective ring need not be self-injective and a right IP-injective ring is not necessarily left IP-injective respectively. 相似文献

We use the theory of triposes to prove that every (non-degenerate) locale H is the set of truth values of a complete and co-complete quasi-topos into which the category of topological spaces embeds and the topos of sheaves over H reflectively embeds. 相似文献

In this paper, a generalization of the class of semicommutative rings is investigated.A ring R is called left GWZI if for any a ∈ R, l(a) is a GW-ideal of R. We prove that a ring R is left GWZI if and only if S3(R) is left GWZI if and only if Vn(R) is left GWZI for any n ≥ 2. 相似文献

Let N be a natural number and A [1, ..., N]2 be a set of cardinalityat least is an absolute constant. We prove that A contains a triple {(k, m), (k+d, m), (k, m+d)},where d > 0. This theorem is a two-dimensional generalizationof Szemerédi's theorem on arithmetic progressions. 2000Mathematics Subject Classification 35J25, 37A15. 相似文献

Let \(V_{n}\) denote the third order linear recursive sequence defined by the initial values \(V_{0}\), \(V_{1}\) and \(V_{2}\) and the recursion \(V_{n}=rV_{n-1}+sV_{n-2}+tV_{n-3}\) if \(n\ge 3\), where r, s, and t are real constants. The \(\{V_{n}\}_{n\ge 0}\) are generalized Tribonacci numbers and reduce to the usual Tribonacci numbers when \(r=s=t=1\) and to the 3-bonacci numbers when \(r=s=1\) and \(t=0\). In this study, we introduced a quaternion sequence which has not been introduced before. We show that the new quaternion sequence that we introduced includes the previously introduced Tribonacci, Padovan, Narayana and third order Jacobsthal quaternion sequences. We obtained the Binet formula, summation formula and the norm value for this new quaternion sequence. 相似文献
