چکیده
Abstract Consider the Hamiltonian action of a torus on transversely symplectic foliation that is also Riemannian. When transverse hard Lefschetz property satisfied, we establish foliated version Kirwan injectivity theorem and use it to study actions Kähler foliations. Among other things, prove analogue Carrell–Liberman theorem. As an application, this confirms conjecture raised by Battaglia–Zaffran basic Hodge numbers toric quasifolds. Our methods allow us present approach calculation Betti

The Kirwan map , equivariant Kirwan maps , and their kernels Lisa
Consider a Hamiltonian action of a compact Lie group K on a compact symplectic manifold. We find descriptions of the kernel of the Kirwan map corresponding to a regular value of the moment map κK . We start with the case when K is a torus T : we determine the kernel of the equivariant Kirwan map (defined by Goldin in [Go]) corresponding to a generic circle S ⊂ T , and show how to recover from t...

متن کاملThe Basic Theorem and its Consequences
Let T be a compact Hausdorff topological space and let M denote an n–dimensional subspace of the space C(T ), the space of real–valued continuous functions on T and let the space be equipped with the uniform norm. Zukhovitskii [7] attributes the Basic Theorem to E.Ya.Remez and gives a proof by duality. He also gives a proof due to Shnirel’man, which uses Helly’s Theorem, now the paper obtains a...
متن کاملBenford Distribution and its Applications
This papers considers the Benford distribution as one the interesting rules of probability theory. This rule shows that, despite of usual underestanding about the uniform distribution of digites for lieing on different positions in numbers, digits are distributed according to an non uniform distributions for numbers araising from many natural phonemena. Benford distribution proposes ...
متن کاملBasic inequality on a b-metric space and its applications
We first prove one of the most basic inequalities on a b-metric space. And then we prove some fixed point theorems. We also consider two similar conditions; one implies the Cauchyness on sequences but the other does not.
