符号运算符空间 OpS_(1,δ)~m 和核分布空间之间的新小波基和等距

一、New Wavelet Bases and Isometric Between Symbolic Operators Spaces OpS_(1,δ)~m and Kernel Distributions Spaces(论文文献综述)

杨奇祥[1](2011)在《Lp CONTINUITY OF HRMANDER SYMBOL OPERATORS OpS0,0m AND NUMERICAL ALGORITHM》文中研究指明If we use Littlewood-Paley decomposition, there is no pseudo-orthogonality for Ho¨rmander symbol operators OpS m 0 , 0 , which is different to the case S m ρ,δ (0 ≤δ < ρ≤ 1). In this paper, we use a special numerical algorithm based on wavelets to study the L p continuity of non infinite smooth operators OpS m 0 , 0 ; in fact, we apply first special wavelets to symbol to get special basic operators, then we regroup all the special basic operators at given scale and prove that such scale operator’s continuity decreases very fast, we sum such scale operators and a symbol operator can be approached by very good compact operators. By correlation of basic operators, we get very exact pseudo-orthogonality and also L 2 → L 2 continuity for scale operators. By considering the influence region of scale operator, we get H 1 (= F 0 , 2 1 ) → L 1 continuity and L ∞→ BMO continuity. By interpolation theorem, we get also L p (= F 0 , 2 p ) → L p continuity for 1 < p < ∞ . Our results are sharp for F 0 , 2 p → L p continuity when 1 ≤ p ≤ 2, that is to say, we find out the exact order of derivations for which the symbols can ensure the resulting operators to be bounded on these spaces.

杨奇祥[2](2007)在《象征算子的紧算子逼近算法和逼近速度》文中研究表明传统的微分方程的方法是利用Taylor展开用主象征逼近象征;本文用充分好的紧算子来逼近象征算子,并且逼近算子在算子范数意义下快速逼近原来的算子.

杨奇祥[3](2003)在《用小波限制紧算子逼近奇异积分算子的速度》文中研究表明根据Beglin-Coifman-Rokhlin和Yang的观点,用合适的小波基可以刻画性地研究C.Z算子或拟微分算子,这样就可以用小波来计算算子.比如可以从奇异积分算子的B-C-R算法刻画出发,用小波限制紧算子进行逼近.本文旨在计算作为原算子与逼近算子的差的误差算子的H1到L1的连续性范数的最佳衰减速度和在 LP上的连续性范数的衰减速度的范围.

YANG Qi Xiang Department of Mathematics. Wuhan University. 430072. Hubei. P. R. China[4](2002)在《New Wavelet Bases and Isometric Between Symbolic Operators Spaces OpS1,δm and Kernel Distributions Spaces》文中研究表明 In the fifties. Calderon established a formal relation between svmbol and kernel distribu-tion, but it is difficult to establish an intrinsic relation. The Calderon-Zygmund (C-Z) school studiedrhe C-Z operators, and Hormander. Kohn and Nirenberg, et al. studied the symbolic operators. Herewe apply a refinement of the Littlewood-Paley (L-P) decomposition, analyse under new wavelet bases.to characterize both symbolic operators spaces OpS1,δm and kernel distributions spaces with other spacescomposed of some ahnost diagonal matrices. then get an isometric between OpS1, δm and kernel distri-bution spaces
