Complex projective varieties are quotients of polydiscs under specific group actions.

We study the rigidity and flexibility of symplectic embeddings of simple shapes. It is first proved that under the condition rn22r12r_n^2 \le 2 r_1^2 the symplectic ellipsoid E(r1,...,rn)E(r_1, ..., r_n) with radii r1...rnr_1 \le ... \le r_n does not embed in a ball of radius strictly smaller than rnr_n. We then use symplectic folding to …

Unified method to calculate Gromov norm for Kähler classes of bounded symmetric domains.

problem Calculating the Gromov norm of Kähler classes for all bounded symmetric domains.
method Combination of ideas from Domin-Toledo and Toledo, aided by the Polydisc Theorem.
result Unified and simplified calculation of Gromov norm for all bounded symmetric domains.

While symplectic manifolds have no local invariants, they do admit many global numerical invariants. Prominent among them are the so-called symplectic capacities. Different capacities are defined in different ways, and so relations between capacities often lead to surprising relations between different aspects of sympl…

We completely solve the symplectic packing problem with equally sized balls for any rational, ruled, symplectic 4-manifolds. We give explicit formulae for the packing numbers, the generalized Gromov widths, the stability numbers, and the corresponding obstructing exceptional classes. As a corollary, we give explicit va…

Let KK be a closed polydisc or ball in $\C^n$, and let YY be a quasi projective algebraic manifold which is Zariski locally equivalent to $\C^p$, or a complement of an algebraic subvariety of codimension 2\ge 2 in such manifold. If rr is an integer satisfying (nr+1)(pr+1)2(n-r+1) (p-r+1)\geq 2 then every holomorphic map from …

A commuting nn-tuple (T1,,Tn)(T_1, \ldots, T_n) of bounded linear operators on a Hilbert space $\clh$ associate a Hilbert module H\mathcal{H} over C[z1,,zn]\mathbb{C}[z_1, \ldots, z_n] in the following sense: \[\mathbb{C}[z_1, \ldots, z_n] \times \mathcal{H} \rightarrow \mathcal{H}, \quad \quad (p, h) \mapsto p(T_1, \ldots, T_n)h…
