ABSTRACT

In this work, we will study a Bessel potential spaces Wαs,p(R+n), (sR, 1p<+, α=(α1,,αn)Rn, α1>12,,αn>12) associated with the Poly-axially operator Δα and their properties. We define the Sobolev-type spaces Eαm,p(R+n) (mN, 0N, 1p<+) and we prove an analogue of Calderón's theorem for Fourier–Bessel transform. We define the nonlinear Bessel potentials associated with a measure ν and the Lαp-capacity. Finally, we establish a classical problem of existence of an extremal function for the Lαp-capacity.

摘要

在这项工作中,我们将研究贝塞尔潜在空间 w ^αsp[R+ñ,(s[R 1个p<+ α=α1个αñ[Rñ α1个>-1个2个αñ>-1个2个)与多轴算子相关 Δα及其属性。我们定义Sobolev型空间Ëαp[R+ñ ñ 0ñ 1个p<+),我们证明了Calderón定理的傅里叶-贝塞尔变换定理的类似物。我们定义了与测度ν相关的非线性贝塞尔电位和大号αp-容量。最后,我们建立了一个极值函数存在的经典问题。大号αp-容量。
