摘要：

We investigate fundamental properties of adjoint functors to the precomposition functor in the category of strict polynomial functors. In particular, we obtain the proof of Touze's Collapsing Conjecture on Ext-groups between twisted functors and refinement of a general program of computing Ext-groups between strict polynomial functors important in representation theory.
