The Heaviside function may be defined as:
* a [[piecewise function]]: <math display="block">H(x) := \begin{cases} 1, & x
* using the [[Iverson bracket]] notation: <math display="block">H(x) := [x>0]</math>
* an [[indicator function]]: <math display="block">H(x) := \mathbf{1}_{x > 0}=\mathbf 1_{\mathbb R_+}(x)</math>
