[Tex/LaTex] How to write abstract and acknowledgement in book format


I need to use this: \documentclass[a4paper,11pt]{book}

I have a main.tex file that organizes all the chapters. There is \frontmatter. In the frontmatter, there is

    \include{acknowledgement }

So, I created 3 files with this name. It kind of works. BUT it does not look like real abstract, ack… or dedication page.

I tried similar to

    My text

It did not work. Can you please point me, how to add, abstract, dedication, acknowledgment?

Best Answer

A few weeks ago I tried to add a dedication and an abstract to my book-document and this is what I found on the net and adapted:


    \null\vspace{\stretch {1}}
                This is the Dedication.


        This is the abstract.


    \bfseries Acknowledgements\end{center}}%
        These are the acknowledgements.


        ... and so on ...
