Finding the slope of a linear function is straightforward. Furthermore the slope is the same at each point on the function. However this is not the case with non-linear functions. A non-linear ...

Let A be a function algebra on a locally compact Hausdorff space. A linear isometry T: A → A is said to be of codimension 1 if the range of T has codimension 1 in A. In this paper, we provide and ...
