I want to use \chapter in above document class. It is showing error saying "undefined control sequence".

I tried using report document class. On \usepackage[english]{babel} it is saying "TeX capacity exceeded, sorry [parameter stack size=10000]. \usepackage[english]". How can I change above document class so that I can use \chapter, \section and all that? Did I add \usepakage that does not work in some documentclasses?

  • As mentioned in an answer amsartdoes not support chapters. Report does, if that did not work for you explain exactly what you tested – daleif Aug 21 '19 at 6:20
  • @daleif It is saying same "undefined control sequence".. – Praphulla Koushik Aug 21 '19 at 6:23
  • On exactly which command? Not \chapter Where does \calclayout come from? And never set margins by hand. Use geometry or similar. – daleif Aug 21 '19 at 6:51
  • @daleif On \usepackage[english]{babel} it is saying "TeX capacity exceeded, sorry [parameter stack size=10000]. \usepackage[english]".. On \calclayout, \address and \email it is showing "undefined control sequence". I copied from some one's file (I dont remember from where).. How to use geometry for margins? – Praphulla Koushik Aug 21 '19 at 6:52

    @daleif \calclayout is the method to be used with AMS classes when you want to change the default page parameters. – egreg Aug 21 '19 at 9:18

amsart is one of a template which supports Journal style, Please use amsbook instead of that, you can get the output:

  • Thanks. It worked.. How can we increase the font, I am hoping to get a book font... – Praphulla Koushik Aug 21 '19 at 6:19
  • @PraphullaKoushik Glad to hear that the suggestion works... Do you want to increase the fontsize to the whole text or any particular part? – MadyYuvi Aug 21 '19 at 6:27
  • to the whole text – Praphulla Koushik Aug 21 '19 at 6:27
  • @PraphullaKoushik Per template maximum size of the text was defined as 12pt, if you need to increase more than this, then define your own...If the answer is useful, then please accept it by clicking the tick mark... – MadyYuvi Aug 21 '19 at 6:30
  • There is no error as such but "\calclayout" is showing in red saying unrecognized command.. samething with \address and \email.. Do I need to worry about this or does it not make a difference? – Praphulla Koushik Aug 21 '19 at 6:32
