We construct a decomposition of the identity operator on the sphere S as a sum of smooth orthogonal projections subordinate to an open cover of S. We give applications of our main result in the study of function spaces and Parseval frames on the sphere.

This paper proposes that the identification of constituents, which is the core problem in grammar induction, can be accomplished by a simple constituency criterion in linguistics: a word/tag sequence which can occur as a fragment is a constituent. Experiment results show that grammar induction by distributional clustering augmented with this criterion achieves good PARSEVAL scores and improves ...

In this paper, we introduce a q-analogue of the P-Widder transform and give a Parseval-Goldstein type theorem. Furthermore, we evaluate the q-Laplace transform of a product of q-Bessel functions. Several special cases of our results are also pointed out.

A new approach to Poisson approximation is proposed. The basic idea is very simple and based on properties of the Charlier polynomials and the Parseval identity. Such an approach quickly leads to new effective bounds for several Poisson approximation problems. A selected survey on diverse Poisson approximation results is also given.

Recently renewed interest in the Lobachevsky-type integrals and interesting identities involving cardinal sine motivate an extension of classical Parseval formula both periodic non-periodic functions. We develop a version that is often more practical applications illustrate its use by extending recent results on integrals. Some previously known, are re-proved transparent manner new formulas for...

this paper is a continuation of [uniformities and covering properties for partial frames (i)], in which we make use of the notion of a partial frame, which is a meet-semilattice in which certain designated subsets are required to have joins, and finite meets distribute over these. after presenting there our axiomatization of partial frames, which we call $sels$-frames, we added structure, in th...

partial frames provide a rich context in which to do pointfree structured and unstructured topology. a small collection of axioms of an elementary nature allows one to do much traditional pointfree topology, both on the level of frames or locales, and that of uniform or metric frames. these axioms are sufficiently general to include as examples bounded distributive lattices, $sigma$-frames, $ka...
