摘要：

We compute the Yoneda extension algebra of the collection of Weyl modules for GL(2) over an algebraically closed field of characteristic p > 0 by developing a theory of generalised Koszul duality for certain 2-functors, one of which controls the rational representation theory of GL(2) over such a field.
