Dimension of affine affine algebras as a module
$begingroup$
Suppose that $Acong mathbb{R}[f_1,dots,f_d]$ is a (commutative) affine $mathbb{R}$-algebra (with identity); where $f_i$ are polynomials $mathbb{R}[x_1,dots,x_N]$. When is $A$ a finite-dimensional $mathbb{R}$-module?
Some examples are
- Simple $mathbb{R}$-algebras,
$mathbb{R}[x]/[x^n]$ (which is an $n$-dimensional vector space)...

What are $f_i$'s? By the way, your second example is missing $x$.

They're polynomials in a polynomial ring (coming from Hilbert's basis theorem)...I made the updates in the question. Thanks for pointing it out :)
