Here are 3 more script fonts for which there exists a LaTeX package (in math mode): Dutchcal(from the esstix 13 font), Boondox (from the stix fonts) (two variants) and Adobe's Bickham. All exist in regular and boldface. The following code allows to test them, commenting and uncommenting the relevant lines:

        \documentclass[12pt]{article}
        \usepackage[utf8]{inputenc}

        \usepackage{dutchcal}
        %\usepackage{boondox-cal}
        %\usepackage{boondox-calo}
        %\usepackage{bickham}

        \pagestyle{empty}

        \begin{document}%
        \textbf{Dutchcal: }
        %\textbf{boondox-cal}
        %\textbf{boondox-calo}
        %\textbf{bickham}
        $ \begin{array}[t]{c@{\quad}c}
            \verb+ \mathcal + & \verb+ \mathbcal + \\[6pt]
            \mathcal{E} & \mathbcal{E}
            \end{array} $

        \end{document}

First, never use $\Pi$ when you obviously mean $\prod$ . Second, I guess dots here between $R_i$ and $ID$ should be centered.

Here is what I got:

\documentclass{article}
\usepackage{amsmath}
\DeclareMathOperator{\Dist}{Dist}
\begin{document}
\pagestyle{empty}
\begin{displaymath}
  MR(e) = \prod_{(R_i\cdot ID, R_j\cdot ID)}
  \underset{\Dist_{sp}(r_i,r_j)\le\delta}{(R_i\bowtie R_j)} 
\end{displaymath}
\end{document}

[Tex/LaTex] How to write above a left-right arrow

You can define an extensible "leftright arrow" by the method explained in Section 38 in Mathmode.pdf by Herber Voß. You can read it with texdoc mathmode on your machine or via this link.

\documentclass{article}
\usepackage{amsmath}

\makeatletter
\newcommand\xleftrightarrow[2][]{%
  \ext@arrow 9999{\longleftrightarrowfill@}{#1}{#2}}
\newcommand\longleftrightarrowfill@{%
  \arrowfill@\leftarrow\relbar\rightarrow}
\makeatother

\begin{document}

$F \xleftrightarrow{\text{DFT}} G$

$F \xleftrightarrow{\text{overlong text}} G$

\end{document}

enter image description here

The optional argument to \xleftrightarrow is for a "under label", so \xleftrightarrow[xyz]{} will have xyz under the arrow, while \xleftrightarrow[xyz]{abc} will have abc over and xyz under the arrow.
