Theorem and Proof In Latex 2

Unnumbered Theorem-Like Environments

To add remarks, comments, note environment or examples to a mathematical document. The amsthm package provides this functionality. It's defined using the starred version of \newtheorem. 

Example:

Suppose I want to have an unnumbered remark environment, I can define the environment like this:

\documentclass[12pt,letterpaper]{article}
% in the preamble:
\newtheorem*{note}{Note}

\begin{document}

% later in the body document:
\begin{note}
This is a note about something.
\end{note}
\end{document}

Proof Environments

Proofs are the core of mathematical papers and books and it is customary to keep them visually apart from the normal text in the document. The amsthm package provides the environment proof for this.
The word Proof is italicized and there is some extra spacing, also a special symbol is used to mark the end of the proof. This symbol ( QED ) can be easily changed, to learn how see the next section.
\documentclass{article}
\usepackage[english]{babel}
\usepackage{amsthm}

\begin{document}
\section{Introduction}
\begin{proof}
Here is some text for the proof.
\end{proof}
\end{document}

Proof Environment With Math Equation

Occasionally you will want to end a proof with an equation; it’s generally a recommended style to the symbol (QED) will appear on a same line by itself, like:
\documentclass{article}
\usepackage[english]{babel}
\usepackage{amsmath}
\usepackage{amsthm}
% use math equation inside proof theorem environment
\begin{proof}
\begin{equation}       % instead of $
f(x)=y\tag*{\qedhere}  % the \tag*{} is new 
\end{equation}         % instead of $
\end{proof}
\end{document}

Changing the QED symbol

The symbol printed at the end of a proof is called the “QED symbol / halmos ”, named after the Hungarian mathematician Paul Halmos, who was renowned for his expository skills. To quote the meaning of QED from Wikipedia:
QED is an initialism of the Latin phrase quod erat demonstrandum, meaning “thus it has been demonstrated”.
It is straightforward to use a symbol, or wording, of your choice to represent the QED symbol. The LaTeX command:
\renewcommand\qedsymbol{$\blacksquare$}
can be used to replace the default white square for a black square printed by $\blacksquare$, the parameter inside the braces. 

Theorem styles

The package amsthm provide special commands to accomplish this.
Here is a list of the possible pre-defined Theorem styles:
  • definition boldface title, Roman body. Commonly used in definitions, conditions, problems, and examples.
    Sample appearance: Definition 2. Definition text.
  • plain boldface title, italicized body. Commonly used in theorems, lemmas, corollaries, propositions and conjectures. (default).
    Sample appearance: Theorem 1. Theorem text.
  • remark italicized title, Roman body. Commonly used in remarks, notes, annotations, claims, cases, acknowledgments and conclusions.
    Sample appearance: Remark 3. Remark text.

Notes: 

  • If you are using either packages with amsmath, you must load amsmath first, example:
    \usepackage{amsmath}
    \usepackage{amsthm}
  • General LaTeX guidelines, Avoid manual formatting, use instead appropriate LaTeX constructs.

Theorem and Proof In Latex 1

Latex documents include elements that require special formatting and numbering such as ( theorems, definitions, propositions, remarks, corollaries, lemmas, problems, examples, conjecture and so on ) in environment.

Minimal Working Example

\documentclass[12pt,letterpaper]{article}
\newtheorem{theorem}{Theorem}
\begin{document}

\section{Introduction}
Theorems can easily be defined:

\begin{theorem}
A definition is an exact and concise explanation of a single concept or word.
\end{theorem}
\end{document}

Numbered Theorems, Definitions, Corollaries and Lemmas

Numbered environments in LaTeX can be defined by means of the command \newtheorem :
\newtheorem{environment name}{Text}[parent counter]
\newtheorem{environment name}[shared counter]{Text}
  1. Put command in the preamble.
  2. The name/label {environment name} of the environment that is defined.
  3. The name {environment name} you will use to reference inside a theorem-like environment \begin{environment name}[environment caption]
    \end{environment name}.
  4. The word {Text/Printed Output} that will be printed, in boldface font, at the beginning of the environment.
  5. The additional argument / optional argument [parent counter/sequential level/numberby/hierarchy name/outer counter] is the name of the sequential level (often by section/subsection/etc.) at which the numbering is to take place / the environment counter is reset every time parent counter is incremented.
  6. The additional argument / optional argument [shared counter/sequential level/numberby/hierarchy name/inner counter] is the name of the sequential level at which the numbering is to take place / the environment counter is reset every time shared counter is incremented.
The statement of any theorem can then be enclosed between \begin{theorem} and \end{theorem}:
\begin{environment name}[environment caption]
\end{environment name}
  1. Put command into the body of your document.
  2. You can put a environment caption / theorem’s traditional name, date, discoverer/scientist, or the similar in square brackets. The environment caption prints at the beginning of the paragraph and inside Parentheses / round bracket.
  3. The theorem will be labelled/titled and numbered by LaTeX, and the statement of the theorem with be automatically italicised.

Referencing Numbers

  • To introduce cross-references, you can give the command \label{name} within the statement of a theorem, lemma, proposition or corollary in order assign the given name to that result. 
  • To reference the number assigned to that result in some other theorem, one gives the command \ref{name}; this will be replaced by the number automatically assigned by LaTeX to that result when the LaTeX program is executed. 
  • We recommend using consistent label names like eq:whatever and sec:whatever, but it is not required.
  • The necessary space above and below the statement of the theorem will automatically be generated by LaTeX.

Example

\documentclass[12pt,letterpaper]{article}
\newtheorem{theorem}{Theorem}[section]
\newtheorem{corollary}{Corollary}[theorem]
\newtheorem{lemma}[theorem]{Lemma}

\begin{document}
\section{Introduction}
Theorems can easily be defined:

\begin{theorem}
Let \(f\) be a function whose derivative exists in every point, then \(f\) is 
a continuous function.
\end{theorem}

\begin{theorem}[Pythagorean theorem]
\label{pythagorean} % To introduce cross-references number
This is a theorem about right triangles and can be summarised in the next 
equation 
\[ x^2 + y^2 = z^2 \]
\end{theorem}

% to assign a referencing numbers
And a consequence of theorem \ref{pythagorean} is the statement in the next 
corollary.

\begin{corollary}
There's no right rectangle whose sides measure 3cm, 4cm, and 6cm.
\end{corollary}

You can reference theorems such as \ref{pythagorean} when a label is assigned.

\begin{lemma}
Given two line segments whose lengths are \(a\) and \(b\) respectively there is a 
real number \(r\) such that \(b=ra\).
\end{lemma}

Notes

  1. By default, each theorem-like uses its own counter. However it is common for similar types of theorems (e.g. Theorems, Lemmas and Corollaries)  to share a counter.
  2. for above example "Theorem 1.2" \label{pythagorean}refers to the 2nd theorem in the 1st section of a document. In this case, specify the theorem in the preamble as follows:
There are three new environments defined in the preamble.
  1. \newtheorem{theorem}{Theorem}[section]
    This is the example presented in the introduction but it has the additional parameter [section] that restarts the theorem counter at every new section.
  2. \newtheorem{corollary}{Corollary}[theorem]
    An environment called corollary is created, the counter of this new environment will be reset every time a new theorem environment is used.
  3. \newtheorem{lemma}[theorem]{Lemma}
    In this case, the even though a new environment called lemma is created, it will use the same counter as the theorem environment. In this case, define subsequent theorems from {theorem}.
