In 2005, non-commutative Iwasawa theory was formulated by Coates, Kato, Fukaya, Kato, and Venjakob. It predicts that a p-adic L-function lies in the first algebraic K-group of certain localized Iwasawa algebra. As a consequence of it, one can predict various congruences between special values of twists of an L-function by various Artin representations, which we consider as non-abelian generalizations of the classical Kummer congruence. I will describe a concrete example of such arising from CM elliptic curves over false Tate curve extensions, and give a sketch of a proof using Hilbert modular forms.
