Ordered reproducing Hilbert spaces over ℂ2Springer Science and Business Media LLC - Tập 24 - Trang 503-510 - 2008
Sheng Zhao Hou, Jie Wang
In this paper, we study the relation between the ordered reproducing Hilbert space and its reproducing kernel. A complete description of a similar and unitary equivalence of two quasi-invariant subspaces generated by polynomials with leading terms is given.
The Neumann Problem for Parabolic Hessian Quotient EquationsSpringer Science and Business Media LLC - Tập 37 - Trang 1313-1348 - 2021
Chuan Qiang Chen, Xi Nan Ma, De Kai Zhang
In this paper, we consider the Neumann problem for parabolic Hessian quotient equations. We show that the k-admissible solution of the parabolic Hessian quotient equation exists for all time and converges to the smooth solution of elliptic Hessian quotient equations. Also solutions of the classical Neumann problem converge to a translating solution.
A criterion of normality based on a single holomorphic functionSpringer Science and Business Media LLC - Tập 27 - Trang 141-154 - 2010
Xiao Jun Liu, Shahar Nevo
Let F be a family of functions holomorphic on a domain D ⊂ ℂ Let k ≥ 2 be an integer and let h be a holomorphic function on D, all of whose zeros have multiplicity at most k −1, such that h(z) has no common zeros with any f ∈ F. Assume also that the following two conditions hold for every f ∈ F: (a) f(z) = 0 ⇒ f′(z) = h(z); and (b) f′(z) = h(z) ⇒ |f
(k)(z)| ≤ c, where c is ...... hiện toàn bộ
Multilinear singular integral operators with generalized kernels and their multilinear commutatorsSpringer Science and Business Media LLC - Tập 33 - Trang 1443-1462 - 2017
Yan Lin, Ya Yuan Xiao
In this paper, the authors study a class of multilinear singular integral operators with generalized kernels and their multilinear commutators with BMO functions. By establishing the sharp maximal estimates, the boundedness on product of weighted Lebesgue spaces and product of variable exponent Lebesgue spaces is obtained, respectively. Moreover, the endpoint estimate of this class of mutilinear s...... hiện toàn bộ
Lattice Structure for Paraunitary Linear–phase Filter Banks with AccuracySpringer Science and Business Media LLC - Tập 22 - Trang 679-688 - 2005
Hong Ying Xiao
Multivariate filter banks with a polyphase matrix built by matrix factorization (lattice structure) were proposed to obtain orthonormal wavelet basis. On the basis of that, we propose a general method of constructing filter banks which ensure second and third accuracy of its corresponding scaling function. In the last part, examples with second and third accuracy are given.
A remark on the generalized second order Toda systemSpringer Science and Business Media LLC - Tập 29 - Trang 1691-1702 - 2013
