Text Formatting ⇒ Numbers of Theorems

[Lumy]

Hello!

Is it possible to enumerate theorems as Theorem A, Theorem B, propositions as Proposition A, .... e.g.:

Proposition A ...............
Theorem B ...........
Theorem C ........
Corrolary D .............
Theorem E .......
Conjecture F ....
I try

Code: Select all

\usepackage{amsthm}
\newtheorem{propA}{Proposition}
\renewcommand{\thepropA}{\Alph{propA}} 
\newtheorem{thmB}{Theorem}
\renewcommand{\thethmB}{\Alph{thmB}} 

but appear: Prosition A, Theorem A ...

Thank you in advance

Hi Lumy,

welcome to the board!

You can share a counter using an optional argument for \newtheorem, such as

Code: Select all

\newtheorem{thmB}[propA]{Theorem}
