$\mathbb{R}^n$中PDMATHAAB-张量场上第一阶$(k+1)$积分矩变换的内射性和值域描述

Rohit Kumar Mishra, Suman Kumar Sahoo

摘要:

本文证明了秩$m$对称张量场的一个新的分解结果,推广了张量场的螺线管分解和势分解。这种分解,然后用来描述内核,并证明一个内射性结果的第一$(k+1)$积分矩变换的对称$m$ -张量场在$\mathbb{R}^n$。此外,我们还提出了一个范围表征的第一$(k+1)$积分矩变换的约翰方程。

英文摘要:

In this work, we prove a new decomposition result for rank $m$ symmetric tensor fields which generalizes the well known solenoidal and potential decomposition of tensor fields. This decomposition is then used to describe the kernel and to prove an injectivity result for first $(k+1)$ integral moment transforms of symmetric $m$-tensor fields in $\mathbb{R}^n$. Additionally, we also present a range characterization for first $(k+1)$ integral moment transforms in terms of the John's equation.
