# \author が指定されていません

このエラーは、\author **`\maketitle`** コマンドを使用したものの、いずれの **`\author`**も指定していない場合に表示されます。例を以下に示します:

```latex
%プリアンブル内で
\title{On the General Molecular Theory of Heat}

% 文書の本文内で
\maketitle
```

main.tex、5行目

\author が指定されていません。

著者を追加することでこのエラーを解決できます:

```latex
%プリアンブル内で
\title{On the General Molecular Theory of Heat}
\author{A. Einstein}

% 文書の本文内で
\maketitle
```

タイトルページに著者を表示したくない場合は、次のように定義できます **`\author{...}`** 以下のように空にします

```latex
%プリアンブル内で
\title{On the General Molecular Theory of Heat}
\author{}

% 文書の本文内で
\maketitle
```

これでも、通常は著者名が書かれるタイトルページ上に、いくらかの空白が残ります。この空白を取り除きたい場合は、 [**`titling`**](http://ctan.org/pkg/titling) パッケージを確認してください。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/ja/latexer/27-no-author-given.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
