Finite ring case

WebJan 24, 2024 · Let R be a finite ring and let ${\mathrm {zp}}(R)$ denote the nullity degree of R, that is, the probability that the multiplication of two randomly chosen elements of R is zero. We establish the nullity degree of a semisimple ring and find upper and lower bounds for the nullity degree in the general case. WebNote. Testing whether a quotient ring \(\ZZ / n\ZZ\) is a field can of course be very costly. By default, it is not tested whether \(n\) is prime or not, in contrast to GF().If the user is sure that the modulus is prime and wants to avoid a primality test, (s)he can provide category=Fields() when constructing the quotient ring, and then the result will behave like a field.

http://match.stanford.edu/reference/finite_rings/sage/rings/finite_rings/integer_mod_ring.html 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.
