Besov數列空間的原子分解

The Atomic Decomposition of Sequence Spaces of Besov type

摘要


在此論文中,作者使用M. Frazier與B. Jawerth引進之原子分解觀念來刻劃Besov數列空間上的正矩陣算子的有界性之充分與必要條件。利用此原子分解,可以應用於「幾米對角矩陣算子」和「Foueier乘積算子」的有界性。

並列摘要


In this note, we use atoms, which were introduced by M. Frazier and B. Jawerth for other sequence spaces, for b(superscript aq subscript p) to characterize the necessary and sufficient conditions for boundedness of a positive operator with matrix {a(subscript QP)}(subscript Q, P) on b(superscript aq subscript p). Then we will give applications to a special type of operators, included the almost diagonal operator, and the Fourier multiplier operators acting on Besov spaces B(superscript aq subscript p).
