This codes compiles a Hasse diagram of a diamond lattice. Now, I want to replace the 0-node by a \wedge b. However, when I replace all instances of 0 by a \wedge b, I get an error. Any help on how to resolve this issue?

\begin{tikzpicture}

  \node [mynode,label=above:1] (1) at (0,0) {};
  \node [mynode,below left  = of 1,label=left:a] (a)  {};
  \node [mynode,below right = of 1,label=right:b] (b) {};
  \node [mynode,below right = of a,label=below:0] (0) {};
  \node [mynode,below       = of 1,label=right:c] (c) {};

  \draw (1) -- (a) 
        (1) -- (c) 
        (1) -- (b)
        (c) -- (0)
        (a) -- (0) 
        (b) -- (0);

\end{tikzpicture}

You are naming a node 0, and node names are converted to macro names. Since it is just a name, use wedge b (no backslash). – John Kormylo Apr 12 '20 at 14:40
Then my node becomes 'a wedge b'. However, I want the mathematical symbol for \wedge. – J.Bosser Apr 12 '20 at 14:43
I deleted the the mynodes, but I still get an error. – J.Bosser Apr 12 '20 at 14:49
@J.Bosser Please add a fully compilable example so we can provide help. – BambOo Apr 12 '20 at 14:51

Doesn't label=below:$\wedge$ work? – Torbjørn T. Apr 12 '20 at 14:57
@TorbjørnT., yes this works! – J.Bosser Apr 12 '20 at 15:00
Another question: how does one places label next to the lines? – J.Bosser Apr 12 '20 at 15:01

Right, just as in normal text, there are things that only works in math mode, and then you need to switch to math mode. A TikZ label/node is no different from normal text in that respect.

To place a label (all labels are really nodes) next to a line, you can use \draw (A) -- (B) node[midway, sloped, above]{text}; – John Kormylo Apr 12 '20 at 15:26
