In this talk, I will introduced the deformed Hermitian Yang-Mills equation. Specifically, I will start from a local model of a section type special Lagrangian submanifold in a complex manifold with semi-flat Calabi-Yau metric. The sympletic structure of the special Lagrangian submanifold will give one some tips how to construct a complex submanifold in the mirror Calabi-Yau manifold. Moreover, this construction is deeply related to the deformed Hermitian Yang-Mills equation.
