AbstractWe prove that the rings of invariants of 2×2 matrices over an infinite field are Cohen–Macaulay. This result generalizes the similar theorem of Mehta and Ramadas in odd characteristics. Our approach is more elementary and it uses only some standard facts from the theory of modules with good filtrations and the theory of determinantal rings
