Understanding the problem

Read the background

A countable characteristic-zero division ring is algebraic over its center, generated by two elements as an algebra over that center, and infinite-dimensional over the center.

Why it matters

If correct, gives a negative answer to the Kurosh problem for division rings.

What counts as progress

Must a finitely generated division ring algebraic over its center be finite-dimensional?
