Symbols:L

The Set of All Linear Transformations
Their LaTeX codes are as follows:
 * $$\mathcal {L}_R \left({G, H}\right)$$ : \mathcal {L}_R \left({G, H}\right)
 * $$\mathcal {L} \left({G, H}\right)$$ : \mathcal {L} \left({G, H}\right)
 * $$\mathcal {L}_R \left({G}\right)$$ : \mathcal {L}_R \left({G}\right)
 * $$\mathcal {L} \left({G}\right)$$ : \mathcal {L} \left({G}\right)

Note
The usual notation for the set of linear transformations involves use of the mathscript font, whose LaTeX code is \mathscr {L}, but this does not render on ProofWiki.
