摘要:
经典的牛顿势,由度量定义,产生定义线性积分算子的基本核家族,并提出线性调和分析的基本问题。当二元度量在集合上的自然特性被推广为集合上的(k+1)元超度量特性时,我们得到k+1变量的核家族,从而产生k阶多线性积分算子或k-线性算子。在同质空间的一般设定下,本文考虑通过基于超度量的势来实现多线性近似到多线性恒等式的难题。
英文摘要:
The classical Newtonian potentials, defined in terms of metrics, give rise to the basic family of kernels defining linear integral operators and posing the fundamental problems of linear harmonic analysis. When the binary character of a metric on a set is naturally generalized to the $(k+1)$-ary character of hypermetric on the set, we obtain families of kernels of $k+1$ variables leading to multilinear integral operators of order $k$ or $k$-linear operators. In this paper we consider the problem of multilinear approximation to the multilinear identity through potentials built on hypermetrics in the general setting of spaces of homogeneous type.
