Hi,

I want the intersection symbol in the file. I tried $\cap$, however that does not work.

I am using

This is LuaTeX, Version snapshot-0.35.0 (Learn_Corbae_Stinchcombe_Zeman.tex

ConTeXt ver: 2009.03.18 21:58 MKIV fmt: 2009.3.31 int: english/english

I get the following error:

! Undefined control sequence. \normalcap ->\dohandlemathtoken {cap} l.25 ...t A $ then $ f(A \cap B) \subset f(A) \cap f(B) $.

Do I need to upgrade to a newer version?

march is pretty old for a mkiv version as in the meantime open type math was added, and support for that in mkiv is under active development (also make sure that you have the latest luatex) using mkiv only makes sense if you update on a regular basis Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
