Vertical Fourier decomposition for skew-Hermitian 1-forms

If $SM$ is trivial (such that you can view it as $M\times \mathbb S^1$ and use the angle $\theta$ to describe the second variable), the $k$th Fourier mode of $\mathbb A\in C^\infty(SM,\mathbb C^{n\...

Threefolds with the same Betti numbers and the same Chern numbers

The complex parallelizable (hence, all Chern classes are trivial) Iwasawa manifold is constructed by taking the complex Lie group of matrices of the form $$\begin{pmatrix} 1 & x & z \\ 0 & ...
