In line: define $$\mathbf{Y}$$ as the network edges, ...

in block:

$$ P(\mathbf{Y} = \mathbf{y}|\mathbf{X}) = exp[{\theta } ^{T} g(\mathbf{y},\mathbf{X})]/k(\theta ) $$

Block equations:

$$ \begin{align} \mbox{Union: } & A\cup B = {x\mid x\in A \mbox{ or } x\in B} \\ \mbox{Concatenation: } & A\circ B = {xy\mid x\in A \mbox{ and } y\in B} \\ \mbox{Star: } & A^\star = {x_1x_2\ldots x_k \mid k\geq 0 \mbox{ and each } x_i\in A} \\ \end{align} $$

Yet another set of block equations:

$$ \begin{align*} 2x - 5y &= 8 \\ 3x + 9y &= -12 \end{align*} $$
