beamer seems to define theorem-environments such as definition, but i want to be able to define them myself. In particular I want to use thmtools.




\title{thmtools + beamer}


Compiling this yields

! LaTeX Error: Command \definition already defined.

but I could not find anything like a \redeclaretheorem command.
