# How to write constraints above or below logical operators in latex? [duplicate]

I want to write constraints below logical operators like or. How do I do it. There is a question already on AND here, how do I do it for OR operator/ other operators like implication etc?

For or, the command would be `\bigvee` although `\bigwedge` and `\bigvee` are symbols which are intended to be used as operators on some set or range of values, e.g.,

`````` \[
\bigwedge_{i=1}^{10} F_{i}
\]
``````

to indicate that you're essentially calculating

F₁ ∧ F₂ ∧ ⋯ ∧ F₁₀

I'm not sure that makes sense for ⇒ which is likely why no such operator is predefined. If you perhaps mean that you want to put some text above or below ⇒ you can load `amsmath` and use the command `\overset`, `\underset` or `\overunderset`, e.g.,

``````\[
A \overset{*}{\Rightarrow} B
\]
``````

to set ⇒ with a * above it. You would do something similar if you wanted to put symbols above or below `\wedge`, `\vee`, etc.
