Image of an isotropic manifold under lagrangian correspondence is isotropic?
Is the following statement well known?
Let $M,N$ be symplectic (algebraic) manifolds. Let $L \subset M \times N$ be a (smooth)
Lagrangian correspondence. For a subset $X \subset M$ we denote $L(X):=( …

Co-normal bundle of orthogonal compliment
Is the following fact well known?
Let $X$ be a manifold and $V$ be a vector space. Let $E_1$ be a sub-bundle of the constant bundle $X \times V$. Let $E_2$ be its orthogonal compliment in $X \tim …

Direct image of Lagrangian subspaces of the co-tangent bundle
Let $p:X \to Y$ be a map of smooth algebraic varieties.
Let $C \subset T^* X$ be a (locally closed) submanifold. Denote by $p_*(C) \subset T^* Y$ the following set:
$$ \{(y,v) \in T^*(Y)\mid\exists …
