I think it is of value to provide the reference. The community is large and is not limited to native English speakers.

comment What is distribution of ratio of two gamma function
@statquant Iverson bracket is an indicator: $x \mapsto [x \elem A]$ is a function equal to 1 whenever $x$ is a member of set $A$ and zero otherwise. As far as I know Kronecker is a special case when domain of the function is a set of integers and $A$ is one element set.

comment Marginal Order Statistics
Given $y_3$ and $y_4$ the range of values of $y_2$ is determined by $ 0 \leqslant y_2 \leqslant y_3$. For given value of $y2$, $y_3$ and $y_4$ the range of values of $y_1$ is determined by $ 0 \leqslant y_1 \leqslant y_2$. Does it make sense?

comment Finding a PDF for a two variable function $W = X - Y$
It should be $\Pr(X \leqslant w_0 + Y) = \int_0^1 \int_{0}^{\max(0, \min(1, y+w_0))} \mathrm{d}x \mathrm{d}y$
