Example 3.22.

Until recently it was believed there are no compact, graded, embedded Lagrangians in ℂm{\mathbin{\mathbb{C}}}^{m}. However, Ekholm, Eliashberg, Murphy and Smith [15, Cor. 1.6] found an example of a compact, graded, embedded Lagrangian 𝒮1×𝒮2{\mathbin{\cal S}}^{1}\times{\mathbin{\cal S}}^{2} in ℂ3{\mathbin{\mathbb{C}}}^{3}, and products give Lagrangian (𝒮1×𝒮2)n({\mathbin{\cal S}}^{1}\times{\mathbin{\cal S}}^{2})^{n}’s in ℂ3​n{\mathbin{\mathbb{C}}}^{3n}. These all have H​F∗HF^{*} obstructed, as they are not strictly immersed.
