Building on Seidel-Solomon’s fundamental work, we define the notion of a g-equivariant Lagrangian brane in a symplectic manifold M if g ⊂ SH 1 (M ) is a sub-Lie algebra of symplectic cohomology of M . This allows us to construct a mirror theory to Bott-Borel-Weil theory on the A-side. We will make our construction completely explicit in the case of sl2 and comment on generalizations to arbitrary semisimple Lie algebras. This is a joint work with James Pascaleff.
