\inlinedefinition An LT-property $P$ is a safety property if for all infinite sequences $t \in \cP(AP)^{\omega}$:
if $t \notin P$ then there is a finite prefix $\hat{t}$ of $t$ such that for every $t'$ with prefix $\hat{t}$, $t \notin P$.

\inlineintuition More informally, it \textit{does not allow anything bad to happen}. Or, more exhaustively, if a sequence $t$ is not allowed by the LT-property,
then there exists a finite prefix $\hat{t}$, which contains everything that makes the sequence violate the LT-property.
Thus, whatever sequence we append to it, it will always remain in violation of the property $P$.

The basic operators are, with $p$ a proposition from $AP \neq \emptyset$, and $\Phi$ and $\Psi$ LTL formulas:
\begin{itemize}
\item $p$ states that it is true ``\textit{now}''
\item $\Phi U \Psi$ states that $\Phi$ holds ``\textit{until}'' $\Psi$ holds. I.e. there are no other valid propositions that hold in between.
\item $\Phi \; U \; \Psi$ states that $\Phi$ holds ``\textit{until}'' $\Psi$ holds. I.e. there are no other valid propositions that hold in between.
\item $\bigcirc \Phi$ states that the $\Phi$ holds for the ``\textit{next}''
