In this paper we use Dedekind zeta functions of two real quadratic number fields at -1 to denote Dedekind sums of high rank.
Our formula is different from that of Siegel’s. As an application, we get a polynomial representation of ζK(-1): ζK(-1) =
1/45(26n3 -41n± 9),n = ±2(mod 5), where K = Q(√5q), prime q = 4n2 + 1, and the class number of quadratic number field K2 = Q(vq) is 1. 相似文献

One of the most important objections to information-based semantic theories is that they are incapable of explaining Frege cases. The worry is that if a concept’s intentional content is a function of its informational content, as such theories propose, then it would appear that coreferring expressions have to be synonymous, and if this is true, it’s difficult to see how an agent could believe that a is F without believing that b is F whenever a and b are identical. I argue that this appearance is deceptive. If we heed the distinction between the analog and digital contents of a signal, it is actually possible to reconstruct something akin to Frege’s sense/reference distinction in purely information-theoretic terms. This allows informational semanticists to treat coreferring expressions as semantically distinct and to solve Frege cases in the same way that Frege did—namely, by appealing to the different contents of coreferring expressions. 相似文献

In order to build the collection of Cauchy reals as a set in constructive set theory, the only power set-like principle needed
is exponentiation. In contrast, the proof that the Dedekind reals form a set has seemed to require more than that. The main
purpose here is to show that exponentiation alone does not suffice for the latter, by furnishing a Kripke model of constructive
set theory, Constructive Zermelo–Fraenkel set theory with subset collection replaced by exponentiation, in which the Cauchy
reals form a set while the Dedekind reals constitute a proper class. 相似文献

In this paper, we study on two subjects. We first construct degenerate analogues of Dedekind sums in the sense of Apostol, Carlitz and Takács, and prove the corresponding reciprocity formulas. Secondly, we define generalized Dedekind character sums, which are explicit extensions of Berndt's definition, and prove the reciprocity laws. From the derived reciprocity laws, we obtain Berndt's reciprocity laws as special cases. 相似文献

We compute the eighth Dedekind number, or the number of monotone collections of subsets of a set with eight elements. The number obtained is 56, 130, 437, 228, 687, 557, 907, 788.Work done while the author was with IDA-CCR, Princeton, New Jersey. 相似文献
