WebSep 26, 2010 · Dimensions of objects in fusion categories are cyclotomic integers, hence number theoretic results have implications in the study of fusion categories and finite depth subfactors. We give two such applications. The first application is determining a complete list of numbers in the interval (2, 76/33) which can occur as the Frobenius-Perron dimension …

In number theory, a cyclotomic field is a number field obtained by adjoining a complex root of unity to Q, the field of rational numbers. Cyclotomic fields played a crucial role in the development of modern algebra and number theory because of their relation with Fermat's Last Theorem. It was in the process of his deep investigations of the arithmetic of these fields (for prime n) – and more precisely, because of the f… WebA28: Robin's Inequality for 20-free Integers Thomas Morrill and David John Platt A29: The Bi-periodic Fibonacci-Horadam Matrix Joy P.

WebApr 11, 2024 · Abstract. Let p>3 be a prime number, \zeta be a primitive p -th root of unity. Suppose that the Kummer-Vandiver conjecture holds for p , i.e., that p does not divide the class number of {\mathbb {Q}} (\,\zeta +\zeta ^ {-1}) . Let \lambda and \nu be the Iwasawa invariants of { {\mathbb {Q}} (\zeta )} and put \lambda =:\sum _ {i\in I}\lambda ... Webeigenvalues are cyclotomic integers. In light of this result, we need only control the repeated eigenvalues and the eigenvalues of the form ζ +ζ−1 for roots of unity ζ.This …

In particular, various
WebThe E n Coxeter diagram, defined for n ≥ 3, is shown in Figure 1. Note that E3 ∼= A2 ⊕ A1.The E n diagram determines a quadratic form B n on Zn, and a reflection group W n ⊂ O(Zn,B n) (see §3).The product of the generating reflections is a Coxeter element w n ∈ W n; it is well-defined up to conjugacy, since E n is a tree [Hum, §8.4]. The Coxeter …
