Quotients of multiplicative forms and Poisson reduction

نویسندگان

چکیده

In this paper we study quotients of Lie algebroids and groupoids endowed with compatible differential forms. We identify theoretic conditions under which such forms become basic characterize the induced on quotients. apply these results to describe generalized quotient reduction processes for (twisted) Poisson Dirac structures, as well their integration by (twisted, pre-)symplectic groupoids. particular, recover generalize several known concerning reduction.

Bounds of Multiplicative Character Sums with Fermat Quotients of Primes

Given a prime p, the Fermat quotient qp(u) of u with gcd(u, p)= 1 is defined by the conditions qp(u)≡ u p−1 − 1 p mod p, 0≤ qp(u)≤ p − 1. We derive a new bound on multiplicative character sums with Fermat quotients qp(`) at prime arguments `. 2010 Mathematics subject classification: primary 11A07; secondary 11L40, 11N25.

Reduction of Poisson Manifolds

Reduction in the category of Poisson manifolds is defined and some basic properties are derived. The context is chosen to include the usual theorems on reduction of symplectic manifolds, as well as results such as the Dirac bracket and the reduction to the Lie-Poisson bracket.

Multiplicative Properties of Integral Binary Quadratic Forms

In this paper, the integral binary quadratic forms for which the set of represented values is closed under k-fold products, for even positive integers k, will be characterized. This property will be seen to distinguish the elements of odd order in the form class group of a fixed discriminant. Further, it will be shown that this closure under k-fold products can always be expressed by a klinear ...

Differential forms and smoothness of quotients by reductive groups

Let π : X −→ Y be a good quotient of a smooth variety X by a reductive algebraic group G and 1 ≤ k ≤ dim (Y ) an integer. We prove that if, locally, any invariant horizontal differential k-form onX (resp. any regular differential k-form on Y ) is a Kähler differential form on Y then codim (Ysing) > k + 1. We also prove that the dualizing sheaf on Y is the sheaf of invariant horizontal dim (Y )-...
