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 $\mu_{i} \rightarrow \mu(t)$ ???? Jul 19, 2020 at 21:25

    I get the expected symbol. Of course, I approve the remark by David.

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.
