¿Cómo escribir texto de tamaño pequeño entre los detallados?

Question

Quiero escribir entre los detalles, es decir, después de una viñeta, quiero agregar 2 oraciones pequeñas debajo. Vea mi código y lo que quiero se proporciona a continuación:

\documentclass{amsart}
 \newtheorem{thm}{Theorem}
 \usepackage{xcolor}

 \begin{document}
 \section{\textcolor{blue}{Testing Nilpotence in linear time}}
 Given a group $G$ in the form of mutiplication table, we want to check to decide  divides the order of $G$}. Algorithm for testing nilpotence is given below. \\

 \begin{itemize}
 \item Compute the prime factorization of $n= p_1^{\alpha_1} \times p_2^{\alpha_2} \cdots p_i^{\alpha_i}$. \\
 \item Determine the order of all elements in $G$. \\
 \item For $1 \le i \le r$, check if $\mathcal{N}(p_i^{\alpha_i}) \neq p_i^{\alpha_i}$ then $G$ is not nilpotent. \\
\item Else output that $G$ is nilpotent  
 \end{itemize}

Pregunta: ¿Cómo agregar texto pequeño como se muestra en la imagen?

Answer 1

Te sugiero que crees una pequeña macro de utilidad llamada \aside. Si \footnotesizeel texto es demasiado pequeño para su gusto, utilícelo \smallen su lugar.

\documentclass{amsart}
\usepackage{xcolor}
\newcommand\aside[1]{\par\quad{\footnotesize(#1)}\par} % or "\small", if you prefer

\begin{document}
\section{\color{blue}Testing Nilpotence in linear time}

Given a group $G$ in the form of multiplication table, we want to check to 
decide [...] divides the order of $G$. An algorithm for testing nilpotence 
is given below.

\begin{itemize}
\item Compute the prime factorization of $n = p_1^{\alpha_1} \times 
     p_2^{\alpha_2} \cdots \times p_i^{\alpha_i}$.
     \aside{Each $p_i^{\alpha_i}$ is the highest power}

\item Determine the order of all elements in $G$. 
     \aside{It can be done easily}

\item For $1 \le i \le r$, check if $\mathcal{N}(p_i^{\alpha_i}) \neq 
     p_i^{\alpha_i}$. If true, $G$ is not nilpotent.

\item Else, conclude that $G$ is nilpotent.
\end{itemize}

\end{document} 

Answer 2

• tu mwe no está completo (falta \end{document})
• también contiene error (superfluo }después $G$)
• todos \\los elementos posteriores son superfluos
• línea adicional debajo del elemento (principal) simplemente escriba en una nueva línea (puede seleccionar un tamaño de fuente más pequeño para esta(s) línea(s))
• para un mejor formato utilice el paqueteenumitem

\documentclass{amsart}
\newtheorem{thm}{Theorem}
\usepackage{xcolor}
\usepackage{enumitem}

\begin{document}
\section{\textcolor{blue}{Testing Nilpotence in linear time}}
Given a group $G$ in the form of multiplication table, we want to check to decide  divides the order of $G$. Algorithm for testing nilpotence is given below. %\\ had to be removed
