Symbol for $\left\{ x \in \mathbb{R} : x > 0 \right\}$

Question

Is there a symbol for the following set?

$$ \left\{ x \in \mathbb{R} : x > 0 \right\} $$

Answer 1

Generally, $\mathbb{R}^+$ is used to denote the positive reals.

Answer 2

I would use $\mathbb R^+$ though some authors use this symbol for $\{x\in\mathbb R: x\geq 0\}$.

Answer 3

I have seen people using $$\mathbb{R}_{>0},(0,\infty)\text{ and also }\mathbb{R}^+$$
