Latex code for the functor Hom_R( _ , X)

[Math Amateur]

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: \(\displaystyle Hom_R( \_ , X)\)

 

[jacobi1]

\(\displaystyle \operatorname{Hom} \_ _R ( \_ ,X)\)
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 ...

,

Thank you for reaching out. The correct LaTeX code for the functor Hom_R( _ , X) is \text{Hom}_R(\_, X). This should display the symbol with the underscore correctly. If you are still having trouble, please provide more context or the specific symbol you are trying to display. I would be happy to assist further.
