In 2001, Brylinski and Deligne classified central extensions
of a reductive group by K_2 and posed one question: How does Tate’s
determinant extension fit into this picture? In this talk, I will
explain an answer to their question. It proceeds by enlarging the
category of central extensions by K_2 and proving that this
enlargement satisfies the expected classification and incorporates
Tate’s extension naturally.
