[Tex/LaTex] Problem with Table of Contents and Chapter on Introduction

header-footertable of contentsthesis

I am currently writing my final master thesis in tex. I am stuck up in the following place. Firstly I have a chapter called Introduction which is not numbered. In the table of contents page, the introduction page starts with a different page number than 1. Ex:enter image description here

Next problem is in the introduction chapter. The heading is different from what it supposed to be. In my template, the first page of the chapter only has a header line with page number and the subsequent pages have the chapter name as header. In this case it is throwing up something else. Ex.
enter image description here

and this is the next page
enter image description here

How to resolve this ?

The third problem is in the table of contents as shown in the figure, "Acknowledgements" and "Abstract" have been assigned some roman numbers. But actually there are no page numbers in the respective tex files. How to set page numbering for these two pages and also incorporate the same in the table of contents. I am also attaching my code in the main file thesis.tex so that it is helpful:

thanks for the help and suggestions.

Best Answer

The first issue should be solvable by using the following after starting your mainmatter:

\setcounter{page}{1}

This resets the page number.

For the second issue, I would use the titlesec package to set the pagestyle of the chapter page:

\assignpagestyle{\chapter}{plain}

This is necessary as the \chapter sets the plain pagestyle by default.
