摘要/Abstract

摘要：

This article has two purposes: the first is to give some structure results for the class of m-isometries, and the second purpose is to extend the notions of left and right inverses to m-left and m-right inverses respectively.

关键词: m-isometry, m-left inverse;, m-right inverse, approximate spectrum, point spectrum
