\subsection{Jensen's inequality}

In its simplest form the inequality states that the convex transformation of a mean is less than or equal to the mean applied after convex transformation(or equivalently, the opposite inequality for concave transformations). 

In the context of probability theory, it is generally stated in the following form: if $X$ is a random variable and $\varphi$ is a convex function, then
\begin{equation*}
    \varphi (\mathbb{E}[X]) \leq \mathbb{E} [\varphi (X)].
\end{equation*}
