Hm, I found the recipe:

 emacs -Q
 load auto-capitalize manually.

Load the following two files

Open a latex buffer and proceed as I said.

The problem is caused by this


 (add-hook 'LaTeX-mode-hook 'my-set-auto-capitalize) 
 (defun my-set-auto-capitalize ()
 (interactive)
         (set (make-local-variable 'auto-capitalize-predicate)
              (lambda () (not (texmathp)))))

That was recommended to me by Kevin in order that
auto-capitalize is deactivated in math environment.

For example
\begin{equation}
 A_i
\end{align}
should not be expanded to 
\begin{equation}
 A_I
\end{align}

The above function provides such a behavior but the price is that change
environment does not work properly. Any thoughts?
