I want to number theorems (or propositions,...) as Theorem 1.1 and Theorem 1.A simultaneously in a text? In fact, I don't know how to mark some theorems (or propositions,...) as Theorem 1.A, Theorem 1.B,...? Thanks for your answers.


One possibility would be to have two theorem-like structures with the same name, but one with arabic numbering and the other one with alphabetic numbering; here's an illustration using the amsthm package:





\chapter{Test Chapter}
Test theorem with arabic numbering.
Test theorem with alphabetic numbering.
Another test theorem with alphabetic numbering.
Another test theorem with arabic numbering.
