On the splitting of infinitesimal Poisson automorphisms around symplectic leaves [PDF]

Differential Geometry and Its Applications, 2018
A geometric description of the first Poisson cohomology groups is given in the semilocal context, around (possibly singular) symplectic leaves. This result is based on the splitting theorems for infinitesimal automorphisms of coupling Poisson structures which describe the interaction between the tangential and transversal data of the characteristic ...

Symplectic leaves of the Gel'fand-Dikii brackets and homotopy classes of nondegenerate curves

Functional Analysis and Its Applications, 1990
The authors prove results such as: the unique continuous invariant of symplectic sheets of the second Gel'fand-Dikij bracket is a monodromy operator and n-degree differential operators generating non-oscillatory equations describe separated symplectic sheets of the same bracket.

Teichmüller spaces as degenerated symplectic leaves in Dubrovin–Ugaglia Poisson manifolds

Physica D: Nonlinear Phenomena, 2012
In this paper we study the Goldman bracket between geodesic length functions both on a Riemann surface $Σ_{g,s,0}$ of genus $g$ with $s=1,2$ holes and on a Riemann sphere $Σ_{0,1,n}$ with one hole and $n$ orbifold points of order two. We show that the corresponding Teichmüller spaces $\mathcal T_{g,s,0}$ and $\mathcal T_{0,1,n}$ are realised as real ...

Torus-invariant prime ideals in quantum matrices, totally nonnegative cells and symplectic leaves [PDF]

Mathematische Zeitschrift, 2010
The algebra of quantum matrices of a given size supports a rational torus action by automorphisms. It follows from work of Letzter and the first named author that to understand the prime and primitive spectra of this algebra, the first step is to understand the prime ideals that are invariant under the torus action.
