Can someone please help me with the correct Latex code for the functor Hom_R( _ , X)
When I try to get the correct symbol for the functor I get $ \displaystyle Hom_R( _ , X)$ , that is I get a symbol without the _ displayed.
Can someone please help me with the correct code?

Hi Peter,
You need to "escape" the underscore with a backslash.
That is: Hom_R( \_ , X)
This shows up as: $ \displaystyle Hom_R( \_ , X)$

$ \displaystyle \operatorname{Hom} \_ _R ( \_ ,X)$
Is that what you want?
Or is it $ \displaystyle \operatorname{Hom}_R ( \_ ,X)$?
The code for the first one is "\operatorname{Hom} \_ _R ( \_ ,X)"the underscore must be preceded by a backslash.
I don't know why an underscore is chosen, though if "_" is an argument of the 'Hom' function, shouldn't it be a letter?

Thanks I like Serena and Jacobi ...
Yes, definitely wanted the symbol $ \displaystyle Hom_R( \_ , X)$ ...
Thanks again for the help ...
