TL;DR
This paper critiques the use of Cartesian-type Kerr-Schild coordinates in Carter’s work, highlighting issues in the maximal extension of the Kerr-Newman solution.
Contribution
It provides a critical analysis of Carter’s maximal extension, identifying flaws related to coordinate choices in Kerr-Newman spacetime.
Findings
Identifies errors in Carter's maximal extension approach
Highlights importance of coordinate systems in Kerr-Newman solutions
Suggests revisions for accurate spacetime extensions
Abstract
We comment on the role of the Cartesian-type Kerr-Schild coordinates in developing a faulty maximal extension of the Kerr-Newman solution in the well-known paper of Carter.
