Schrodinger算子Poisson积分的BMO迹刻画

On characterization of Poisson integrals of Schrodinger operators with BMO traces

Xuan Thinh Duong, Lixin Yan, Chao Zhang

摘要:

设L是作用在L^2(Rn)上的薛定谔算子L=-Δ+V,其中非负势V属于逆Holder类Bq,其中q>= n。设BMO_L(Rn)表示Rn上与Schrodinger算子L相关联的BMO空间.本文证明了BMO_L(Rn)中的函数f是L ′ u =-u_tt+Lu=0,u(x,0)= f(x)的解的迹,其中u满足Carleson条件.反之,这个Carleson条件刻画了所有迹属于空间BMO_L(Rn)的L-调和函数。这一结果推广了Fabes,Johnson和Neri对John和Nirenberg的经典BMO空间的类似刻画。

英文摘要:

Let L be a Schrodinger operator of the form L=-Δ+V acting on L^2(Rn) where the nonnegative potential V belongs to the reverse Holder class Bq for some q>= n. Let BMO_L(Rn) denote the BMO space on Rn associated to the Schrodinger operator L. In this article we will show that a function f in BMO_L(Rn) is the trace of the solution of L'u=-u_tt+Lu=0, u(x,0)= f(x), where u satisfies a Carleson condition. Conversely, this Carleson condition characterizes all the L-harmonic functions whose traces belong to the space BMO_L(Rn). This result extends the analogous characterization founded by Fabes, Johnson and Neri for the classical BMO space of John and Nirenberg.
