Cohomology of symplectic $T^{n}$ - reductions and compactifications of $M_{0, n}$

Victor M. Buchstaber, Svjetlana TerziÄ

A symplectic $T^{n}$ - reduction on a complex Grassmann manifold $G_{n, 2}$ for the canonical action of the maximal compact torus depends on the $S_{n}$ - orbit of a maximal chamber in…

Smooth manifolds in $G_{n, 2}$ and $C P^{N}$ defined by symplectic reductions of $T^{n}$ -action

Victor M. Buchstaber, Svjetlana TerziÄ

PlÃ¼cker coordinates define the $T^{n}$ -equivariant embedding $p : G_{n,2}\to \C P^{N}$ of a complex Grassmann manifold $G_{n, 2}$ into the complex projective space $\C P^{N}$, $N=\bi…
