induced maximal ideals in ring of functions [on hold]












1














Let $R$ be a ring and $X$ be a non-empty set.

We know that $operatorname{Map}(X,R) = {f : X to R}$ is a ring

where, $(f+g)(x)= f(x) + g(x)$ and $(fcdot g)(x)=f(x)cdot g(x)$


I want to know that if $M$ is a maximal ideal in $R$ whether this ideal induces a maximal ideal in $operatorname{Map}(X,R)$?

          Not only one, but sometimes many. For each $xin X$ and maximal ideal $M$, you can consider the subset of functions $f$ such that $f(x)in M$. If you check, you'll find this is a maximal ideal of the set of functions.



          It is not always the case that these are all the maximal ideals, though.
