在多项式体积增长的李群G上,引入了与任意次拉普拉斯算子相关的Littlewood-Paley分解;这使我们能够在这种一般情况下证明Littlewood-Paley定理,并通过热核提供Besov空间B s,q p (G), s∈v的二进表征,等价于经典定义。(©2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
We introduce a Littlewood–Paley decomposition related to any sub‐Laplacian on a Lie group G of polynomial volume growth; this allows us to prove a Littlewood–Paley theorem in this general setting and to provide a dyadic characterization of Besov spaces B s,q p (G ), s ∈ ℝ, equivalent to the classical definition through the heat kernel.
