single column abstract in an article and delete date below title

Question

I am using LyX to prepare my journal for publication using article style.

I use double column article. When I choose abstract from left panel, the abstract turns out to be in left-column in double column in pdf output.

I searched around in LyX, but I could not find any option for making the abstract to be in single column and following texts to be in double columns.

Further, I want the date below the title line to be removed in pdf output.

How can these be achieved? I wish I can get some help and appreciate any help in advance.

Answer 1

One column abstract

The LaTeX equivalent of your question is How can I place a one-column-abstract in a two-column document?, and this is also mentioned in the FAQ.

To do this in LyX you'll need to use ERTs I think, which is inserted with Ctrl+L.

1. At the very beginning of your document, before author, title, etc., add an ERT where you write

    \twocolumn[
      \begin{@twocolumnfalse} 
   

2. Add author, title from the top-left drop down menu.

3. Add your abstract.

4. After the abstract, make sure you're outside the abstract environment, e.g. by selecting the Standard style from the drop down menu. Then add an ERT with

    \end{@twocolumnfalse}
    ]
   

If you look in the source preview panel, you should see code similar to this:

\twocolumn[
  \begin{@twocolumnfalse}
\author{Who}
\title{What?}
\maketitle
\begin{abstract}
Stuff.
\end{abstract}
 \end{@twocolumnfalse}
]

Remove date

Go to Document --> Settings --> LaTeX Preamble, add

\date{}

I used the lipsum package and its \lipsum command to create some dummy text for this screenshot.
