Cannot put integral in Beamer presentation

Question

EDIT: I've found a solution thanks to this topic: beamer over miktex 2.9 is not working with math environment In any case, thanks to everyone who posted an answer!

I'm struggling to put an integral in this presentation. Here's the code

\documentclass{beamer}
\usepackage{relsize}
\usepackage[english]{babel} 
\usepackage{amsmath,amsfonts,amsthm,bm}
\title{PCA for functional data}
\author{Carlo Schiano di Cola}
\date{21/07/2020}
\begin{document}
% [..]
\begin{frame}
\frametitle{Introduction}
Some concepts from the multivariate analysis can be imported in the functional context
\LARGE
x\textsubscript{i} $\rightarrow$ x(t)
$\mu$\textsubscript{i} $\rightarrow$ $\mu$(t)
$\Sigma$\textsubscript{ij} $\rightarrow$ v(s,t)
\begin{equation}
\int_{a}^{b} x(t)y(t)dt
\end{equation}
\end{frame}
\end{document}

The error I get says only that

MikTeX Compiler Driver did not succeed

why $\mu$\textsubscript{i} $\rightarrow$ $\mu$(t) rather than more normal markup such as $\mu_{i} \rightarrow \mu(t)$ ???? — David Carlisle, Jul 19 '20 at 21:25
I get the expected symbol. Of course, I approve the remark by David. — egreg, Jul 19 '20 at 21:44

I suggest you replace the inline-math formulas

x\textsubscript{i} $\rightarrow$ x(t)
$\mu$\textsubscript{i} $\rightarrow$ $\mu$(t)
$\Sigma$\textsubscript{ij} $\rightarrow$ v(s,t)

with

$x_i \to x(t)$
$\mu_i \to \mu(t)$
$\Sigma_{ij} \to v(s,t)$

Observe the use of (a) a single pair of $ delimiters per formula and (b) the _ ("underscore") character to initiate subscript-level material.
