Webthe group ring of a finite group over an abelian number field will be (Morita) equivalent to a cyclotomic algebra over a (possibly larger) abelian number field F (see [15]). This meansthat the simple component FGe correspondingto χ ∈ Irr(G) can be expressed as a matrix ring over a cyclotomic algebra with center F(χ), WebOur line of Naval Quarterdeck products feature commonly used items such as ceremonial wood quarterdeck bullets,chrome missile stanchions,ceremonial bullet ropes, port and …

Webring-LWE problem [LPR10], which in turn is the heart of many ideal-lattice-based cryptosystems. The attack fails on approx-SVP because most ideals in cyclotomic rings are not principal, and moreover, most principal ideals do not have short generators (as compared with their shortest nonzero elements).

A CATEGORIFICATION OF CYCLOTOMIC RINGS - arXiv
The cyclotomic polynomials are monic polynomials with integer coefficients that are irreducible over the field of the rational numbers. Except for n equal to 1 or 2, they are palindromics of even degree. The degree of , or in other words the number of nth primitive roots of unity, is , where is Euler's totient function. Webrestores unique factorization for the rings in question. To begin a study of this theory, we start by investigating the elements of the rings of integers of cyclotomic elds, which Kummer called cyclotomic integers. De nition 1.1.
