Create Latex Lemma 1.1: No Indentation Needed

[tgt]

Just say you are inside a lemma, which Latex automatically labels as Lemma 1. You'd like another lemma inside this one, call Lemma 1.1, what command do you type?

How do you make it so that when a new paragraph starts, no indenting appears?

You could probably do something by defining a command "sublemma", setting up a counter, etc. But why on Earth would you want to have a lemma inside a lemma? Instead of trying to make this in LaTeX, I'd strongly recommend revising the structure of your document. I don't know what you are writing, but you could for example call the sublemma a Lemma and then call the original lemma a proposition, theorem or corollary.

As for the second one, you can cancel the indentation of a particular paragraph by putting \noindent at the start. If you don't want any indentation at all, you can just set the parskip to zero:

\parskip0em

To create Lemma 1.1 inside Lemma 1, the command to use is \begin{lemma} and \end{lemma}. This will automatically label the inner lemma as Lemma 1.1. To remove indentation for a new paragraph, use the command \noindent at the beginning of the paragraph. This will prevent the paragraph from being indented.
