\section{\large Introduction}
 % Example of Definition
 
\begin{definition}
{\rm Text of the definition.}
\end{definition}

 % Example of Remark
 
\begin{remark}
{\rm Text of the remark.}

\end{remark}


 % Example of Theorem
 
\begin{theorem}\label{th1}
Text of the theorem.

\end{theorem}

\begin{proof}
Text of the proof of theorem
\end{proof}

 

 % Example of Lemma
 \begin{lemma}\label{lem1}
Text of the lemma.
\end{lemma}

\begin{proof}
Text of proof of the lemma
\end{proof}

 % Example of Corollary
 \begin{corollary}\label{cor1}
Text of the corollary.
\end{corollary}

\begin{proof}
Text of proof of the corollary
\end{proof}

For each group of objects, use its own numbers. (e.g. Theorem 1.1, Theorem 1.2,... Lemma 1.1, Lemma 1.2, ... Corollary 1.1, Corollary 1.2,...)
\\

 % Examples of formulas

 Use double dollars for separate formulas:
 $$
 y=f(x), \quad x\in\mathbb{R}.
 $$
 Number formulas as follows:
\begin{equation}\label{1.1}
 y=f(x), \quad x\in\mathbb{R}.
\end{equation}
