Let G be a nonempty closed subset of a Banach space X.Let B(X)be the family of nonempty bounded closed subsets of X endowed with the Hausdorff distance and BG(X)={A∈B(X):A∩G=φ},where the closure is taken in the metric space(B(X),H).For x∈X and

假设薛定谔算子L=-△+V中的非负位势函数V属于反向Hölder函数类RHs(n/2≤s<n),我们给出了Riesz变换Tα,β-Vα▽L-β的Hardy型估计.这个结论实质性地推广了已知结果.
Assume thatτis a finite dimensional complex Lie superalgebra with a non-degenerate super-symmetric invariant bilinear form,p is a finite dimensional complex super vector space with a nondegenerate super-symmetric bilinear form,and v:τ→osp(p)is a homomorph
By the new spectrum originated from the single-valued extension property,we give the necessary and sufficient conditions for a bounded linear operator defined on a Banach space for which property(ω)holds.Meanwhile,the relationship between hypercyclic prop
Define the differential operators φn for n∈N inductively by φ1[f](z)=f(z)and φn+1[f](z)=f(z)φn[f](z)+d/daφn[f](z).For a positive integer k≥2 and a positive number δ,let F be the family of functions f
介绍了电磁学中库仑(Coulomb)定律和麦克斯韦(Maxwell)方程组建立的历史过程.通过对Coulomb定律的建立和完善过程的分析,阐释了建立一个物理定律需要经历的步骤,对学生科学思维的培养具有一定促进意义;通过对Maxwell方程组建立过程的讨论,阐明了物理定律的层次性和科学美学观念,对激发学生学习兴趣有一定的积极作用.
In this paper,we prove that the weighted BMO space BMOp(ω)={f∈L1loc:sup||χQ||-1Lp(ω)||(F-Fq)ω-1χQ||LP(ω)<∞Q}is independent of the scale p∈(0,∞)in sense of norm whenω∈A1.Moreover,we can r
