I want to state that a robot needs to be inside a bounded area. I would like to have a nice short expression like the one below:
$$x \in \mathbb{R}_+^2$$
But what I actually mean is the following:
$$ x_1 \in (0,x_{lim}] \\ x_2 \in (0,y_{lim}] $$
Which looks rather bulky, and is not easily generalized to higher dimensions. Is there any compact way of stating this?
