Let ( I )$( I )$ be an ideal in the ring ( R )$( R )$ of all holomorphic functions of a single complex variable on the complex plane. I am interested in understanding whether it is possible for ( I )$( I )$ to be non-finitely generated.
Has there been any prior research on this specific question, or are there known conditions under which an ideal in ( R )$( R )$ would necessarily be finitely generated or not? Any insights, references, or approaches would be greatly appreciated.
