Convexity of the moment map image for torus actions on bm -symplectic manifolds. [PDF]
Philos Trans A Math Phys Eng Sci, 2018 We prove a convexity theorem for the image of the moment map of a Hamiltonian torus action on a bm-symplectic manifold. This article is part of the theme issue ‘Finite dimensional integrable systems: new trends and methodsPeer ReviewedPostprint ...

Commutative C⁎-Algebras of Toeplitz Operators via the Moment Map on the Polydisk [PDF]
Journal of Function Spaces, 2016 We found that in the polydisk Dn there exist (n+1)(n+2)/2 different classes of commutative C⁎-algebras generated by Toeplitz operators whose symbols are invariant under the action of maximal Abelian subgroups of biholomorphisms.

Quantum Moment Map and Invariant Integration Theory on Quantum Spaces
Acta Polytechnica, 2011 It is shown that, on the one hand, quantum moment maps give rise to examples for the operator-theoretic approach to invariant integration theory developed by K.-D.

Isotropic maps and moment map flow
We consider the moduli space of isotropic maps from a closed surface $Σ$ to a symplectic affine space and construct a Kähler moment map geometry, on a space of differential forms on $Σ$, such that the isotropic maps correspond to certain zeroes of the moment map.

Entropy, 2016 We introduce the symplectic structure of information geometry based on Souriau’s Lie group thermodynamics model, with a covariant definition of Gibbs equilibrium via invariances through co-adjoint action of a group on its moment space, defining physical ...

A Remark on the Moment Map [PDF]
Proceedings of the American Mathematical Society, 1994 Following S. Lie, it is proposed that moment maps be constructed for degenerate forms and the utility of such maps is illustrated by computing the moment maps for torus actions on C n {{\mathbf {C}}^n} and U ( n )

Bott-Samelson Varieties, Subword Complexes and Brick Polytopes [PDF]
Discrete Mathematics & Theoretical Computer Science, 2014 Bott-Samelson varieties factor the flag variety $G/B$ into a product of $\mathbb{C}\mathbb{P}^1$'s with a map into $G/B$. These varieties are mostly studied in the case in which the map into $G/B$ is birational; however in this paper we study fibers of ...

Mathematical Research Letters, 2001 In this paper the author proves an extension of a theorem, due to \textit{L. Ness} [Am. J. Math. 106, 1281--1329 (1984; Zbl 0604.14006), theorem 6.2] to the case of real group actions. Let \(G\) be a real semisimple Lie group with Cartan-decomposed algebra \({\mathbf g}={\mathbf l}+{\mathbf p}\).
