一类非紧流形上的调和Bergman空间、泊松方程和Hardy型空间的对偶

Harmonic Bergman spaces, the Poisson equation and the dual of Hardy-type spaces on certain noncompact manifolds

G. Mauceri, S. Meda, M. Vallarino

摘要:

本文考虑具有有界几何和谱间隙的完备连通非紧黎曼流形M。本文将Hardy型空间X^h(M)的对偶空间Y^h(M)实现为满足适当的BMO-类条件的局部平方可积〔的〕函数类,其中常数的作用由整体k-拟调和函数空间发挥.进一步证明了Y^h(M)也是X ^k-原子有限线性组合空间X^k_fin(M)的对偶。因此,如果Z是巴拿赫空间,T是定义在X^k_fin(M)上的Z值线性算子,则T扩张为从X^k(M)到Z的有界算子当且仅当它在X^k-原子上一致有界。为了得到这些结果,我们证明了广义泊松方程L^ku=f(f在L^2_loc(M)中)的整体可解性,并研究了测地球上调和函数的广义Bergman空间的一些性质.

英文摘要:

In this paper we consider a complete connected noncompact Riemannian manifold M with bounded geometry and spectral gap. We realize the dual space Y^h(M) of the Hardy-type space X^h(M), introduced in a previous paper of the authors, as the class of all locally square integrable functions satisfying suitable BMO-like conditions, where the role of the constants is played by the space of global k-quasi-harmonic functions. Furthermore we prove that Y^h(M) is also the dual of the space X^k_fin(M) of finite linear combination of X^k-atoms. As a consequence, if Z is a Banach space and T is a Z-valued linear operator defined on X^k_fin(M), then T extends to a bounded operator from X^k(M) to Z if and only if it is uniformly bounded on X^k-atoms. To obtain these results we prove the global solvability of the generalized Poisson equation L^ku=f with f in L^2_loc(M) and we study some properties of generalized Bergman spaces of harmonic functions on geodesic balls.
