Theorem 1.

For every maximal dual Δd\Delta_{d}-complex Π\Pi there exists a stratified TnT^{n}-fibration λ:V→Π¯\lambda:V\to\bar{\Pi} . This fibration satisfies to the following properties

  • •

    the induced map λ∗:Hn​(Π¯,ℤ)→Hn​(V,ℤ)\lambda^{*}:H^{n}(\bar{\Pi};\mathbb{Z})\to H^{n}(V;\mathbb{Z}) is injective, where Hn​(Π¯,ℤ)≈ℤpgH^{n}(\bar{\Pi};\mathbb{Z})\approx\mathbb{Z}^{p_{g}}, pg=hn,0p_{g}=h^{n,0} is the geometric genus of VV;

  • •

    for each primitive piece UjU_{j} of Π\Pi (see Definition 5) the inverse image λ−1​(Uj)\lambda^{-1}(U_{j}) is an open pair-of-pants 𝒫n\mathcal{P}_{n}.

  • •

    for each nn-cell ee of Π¯\bar{\Pi} there exists a point x∈ex\in e such that the fiber λ−1​(x)\lambda^{-1}(x) is a Lagrangian nn-torus Tn⊂VT^{n}\subset V;

  • •

    there exist Lagrangian embedding ϕk:Sn→V\phi_{k}:S^{n}\to V, k=1,…,pgk=1,\dots,p_{g} such that the cycles λ⁡(ϕk​(Sn))\lambda(\phi_{k}(S^{n})) form a basis of Hn​(Π¯)H_{n}(\bar{\Pi}).

Maximal dual Δd\Delta_{d}-complexes exist for every degree dd and every dimension nn.
