Finite ring case
WebJack Schmidt's answer can be further defend by this analogy: Cayley's theorem for groups is analogous to Cayley's theorem for semigroups, using the semigroup of all endomorphisms of a set. Then a unital semigroup is to a set as a unital ring is to an abelian group, so taking all of the endomorphisms of that group is again the same kind of theorem. WebJan 30, 2024 · 14. In the course I'm studying, if I've understood it right, the main difference between the two is supposed to be that finite fields have division (inverse multiplication) while rings don't. But as I remember, rings also had inverse multiplication, so I …

WebDefinition 10.122.3. Let R \to S be a finite type ring map. Let \mathfrak q \subset S be a prime. If the equivalent conditions of Lemma 10.122.2 are satisfied then we say R \to S is quasi-finite at \mathfrak q. We say a ring map A \to B is quasi-finite if it is of finite type and quasi-finite at all primes of B. Webtities of a finite-ring are finitely based; the arithmetical ring case is shown by H. Werner and R. Wille [13]. From [6], it also follows that a finite ring generates a variety containing only finitely many subvarieties. We show here that the converse is also true. If U and 13 are ring varieties, then the class

We decompose the ring R by using orthogonal idempotents Δ1,Δ2,Δ3, and Δ4 as R=Δ1R⊕Δ2R⊕Δ3R⊕Δ4R, and to construct quantum-error-correcting (QEC) codes over R. As an application, we ...
