%0 Journal Article %T Categorification of the ring of cyclotomic integers for products of two primes %A Djalal Mirmohades %J Mathematics %D 2015 %I arXiv %X Let $n$ be a product of two distinct prime numbers. We construct a triangulated monoidal category having a Grothendieck ring isomorphic to the ring of $n$:th cyclotomic integers. %U http://arxiv.org/abs/1506.08755v1
