Let be an exact Lagrangian submanifold of a cotangent bundle , asymptotic to a Legendrian submanifold . We study a locally constant sheaf of -categories on , called the sheaf of brane structures or . Its fiber is the -category of spectra, and we construct a Hamiltonian invariant, fully faithful functor from to the -category of sheaves of spectra on with singular support in .

微局域束理论中的膜结构

让是余切丛的精确拉格朗日子流形，渐近到传奇子流形。我们研究一个局部恒定的束- 类别，称为膜结构束或。它的纤维是-谱类别，我们构造一个哈密顿不变的、完全忠实的函子到- 光谱束类别在单一支持下。
