The Universal Generating Function of Analytical Poisson Structures
The notion of generating functions of Poisson structures was first studied in
math.SG/0312380.They are special functions which induce, on open subsets of
, a Poisson structure together with the local symplectic groupoid
integrating it. A universal generating function was provided in terms of a
formal power series coming from Kontsevich star product. The present article
proves that this universal generating function converges for analytical Poisson
structures and compares the induced local symplectic groupoid with the phase
space of Karasev--Maslov.Comment: 15 pages, 2 figures, shorter version, introductive part remove
Deformation quantization of Leibniz algebras
This paper has two parts. The first part is a review and extension of the
methods of integration of Leibniz algebras into Lie racks, including as new
feature a new way of integrating 2-cocycles (see Lemma 3.9).
In the second part, we use the local integration of a Leibniz algebra h using
a Baker-Campbell-Hausdorff type formula in order to deformation quantize its
linear dual h^*. More precisely, we define a natural rack product on the set of
exponential functions which extends to a rack action on C^{\infty}(h^*).Comment: 37 pages, added explicit computation of the first term of the
deformation, i.e. the bracket which is to be quantize
Tensor products of representations up to homotopy
We study the construction of tensor products of representations up to
homotopy, which are the A-infinity version of ordinary representations. We
provide formulas for the construction of tensor products of representations up
to homotopy and of morphisms between them, and show that these formulas give
the homotopy category a monoidal structure which is uniquely defined up to
equivalence.Comment: 42 pages, 2 figure
Integration of Lie Algebroid Comorphisms
We show that the path construction integration of Lie algebroids by Lie
groupoids is an actual equivalence from the category of integrable Lie
algebroids and complete Lie algebroid comorphisms to the category of source
1-connected Lie groupoids and Lie groupoid comorphisms. This allows us to
construct an actual symplectization functor in Poisson geometry. We include
examples to show that the integrability of comorphisms and Poisson maps may not
hold in the absence of a completeness assumption.Comment: 28 pages, references adde
The Universal Generating Function of Analytical Poisson Structures
Generating functions of Poisson structures are special functions which induce, on open subsets of , a Poisson structure together with the local symplectic groupoid integrating it. In a previous paper by A. S. Cattaneo, G. Felder and the author, a universal generating function was provided in terms of a formal power series coming from Kontsevich star product. The present article proves that this universal generating function converges for analytical Poisson structures and shows that the induced local symplectic groupoid coincides with the phase space of Karasev-Maslo
Symplectic Microgeometry III: Monoids
We show that the category of Poisson manifolds and Poisson maps, the category
of symplectic microgroupoids and lagrangian submicrogroupoids (as morphisms),
and the category of monoids and monoid morphisms in the microsymplectic
category are equivalent symmetric monoidal categories.Comment: 19 pages, 2 figure
