Test post

This is a post to test compilation with pandoc.

Display maths: \[G_{ab} + g_{ab} = T_{ab}\] \[G_{ab} := R_{ab} - \frac12 R g_{ab}\]

But inline maths should also work, e.g. \(F(b) - F(a) = _a^b f(x) , x\) is equivalent to \(\frac{\mathrm d}{\mathrm d x}\,F(x) = f(x)\).

Does align work as an environment?

\[\begin{align*} a &= b \\ &= c \end{align*}\]

What about negative space? \(ab \quad a\!b \quad a\,b\)
