Possible solution with tikz-cd as been suggested in the comments.

\documentclass[tikz]{standalone}
\usepackage{tikz-cd}
\usepackage{amsmath}
\begin{document}

\begin{tikzcd}
y  \ar{r}{(E)} & v(y) \ar{r}{(T)} & T_{s}(v(y)) \ar{r} & \min\limits_{s \in S} T_{s}(v(y))\\
y^{*} \ar[equal]{d} \ar{r}{(E)} & v(y) \ar{r}{(T)} & T_{s}(v(y^{*})) \ar{d} \\
(y_{s})_{s \in S} \ar{r} {y^{*}_{s} > 0}& y^{*}_{s} \ar[equal]{r} & \min\limits_{s \in S}T_{s}(v(y^{*})) &
\end{tikzcd}

\end{document}

  • Please ask an independent question regarding the problem you're facing plus the code that generates the problem. – CroCo Jul 16 '16 at 22:17
