 Let L be a reductive Lie algebra. The strong Macdonald theorems of Fishel, Grojnowski, and Teleman state that the cohomology algebras of L[z]/zN and L[z,s] (where s is an odd variable) are free skew-commutative algebras with generators in certain degrees. The theorems were originally conjectured by Hanlon and Feigin as Lie algebra cohomology extensions of Macdonald's constant term conjecture for an untwisted affine root system. I will explain how to get strong Macdonald theorems for the fixed-point subalgebras of L[z]/zN and L[z,s] under a diagram automorphism twist. These twisted strong Macdonald theorems are Lie algebra cohomology versions of Macdonald's constant term conjecture for twisted affine root systems. I will also explain how to calculate the cohomology algebra of p/zNp and p[s] when p is a parahoric in a twisted loop algebra. In this case the cohomology of p/zNp is not necessarily free, as it contains a factor which is isomorphic to the cohomology algebra of flag variety for the corresponding parabolic.
