Polynomial subalgebras in two dimensions
In this project we look at subalgebras of the polynomial ring i two variables of low codimension. To such a subalgebra is associatied a finite set of points in
called the Spectrum. Polynomials belong to the subalgebra if and only if they satisfy a (small) number of conditions on the polynomial and some of its directional derivatives in the spectral points. We want to classify such subalgebras.
