The moment maps in diffeology [PDF]

open access: yesMemoirs of the American Mathematical Society, 2010
This memoir presents a generalization of the moment maps to the category {Diffeology}. This construction applies to every smooth action of any diffeological group G

A cohomological framework for homotopy moment maps [PDF]

open access: yesJournal of Geometry and Physics, 2015
International audienceGiven a Lie group acting on a manifold M preserving a closed n+1-form ω, the notion of homotopy moment map for this action was introduced in [FRZ], in terms of L∞-algebra morphisms.

Quantum moment maps [PDF]

open access: yes, 2019
We introduce quantum versions of Manin pairs and Manin triples and define quantum moment maps in this context. This provides a framework that incorporates quantum moment maps for actions of Lie algebras and quantum groups for any quantum parameter.

Manin pairs and moment maps revisited [PDF]

open access: yesJournal of Geometry and Physics
The notion of quasi-Poisson $G$-spaces with $D/G$-valued moment maps was introduced by Alekseev and Kosmann-Schwarzbach in 1999. Our main result is a \emph{Lifting Theorem}, establishing a bijective correspondence between the categories of quasi-Poisson $

Moment shadow mapping

Proceedings of the 19th Symposium on Interactive 3D Graphics and Games, 2015
We present moment shadow mapping, a novel technique for fast, filtered hard shadows. Like variance shadow mapping it allows for the application of all kinds of efficient texture filtering and antialiasing to its moment shadow map. However it is designed to provide a substantially higher quality. Moment shadow maps store four moments of the depth within

Dual pairs of quantum moment maps and doubles of Hopf algebras [PDF]

open access: yesJournal of Algebra, 2017
For any finite-dimensional Hopf algebra A there exists a natural associative algebra homomorphism D(A)→H(A) between its Drinfeld double D(A) and its Heisenberg double H(A). We construct this homomorphism using a pair of commuting quantum moment maps, and

Homogeneous isoparametric hypersurfaces in spheres with four distinct principal curvatures and moment maps [PDF]

open access: yesTohoku Mathematical Journal, 2010
We study relations between moment maps of Hamiltonian actions and isoparametric hypersurfaces in spheres with four distinct principal curvatures. In this paper, we deal with the isoparametric hypersurfaces given by the isotropy representations of compact
