Thanks for nabla. I can handle the commands for multiple integrals by myself in the way I sketched before. Contour integral \oint is working but not correctly in my case. This code: \starttext \startformula \oint\limits_{\partial S} \vec{F}\cdot{\rm d}\vec{l}=\mathop{\int\!\!\!\int}\limits_{\bs S\phantom{M}} \vec{\nabla} \times \vec{F}\cdot{\rm d}\vec{S} \stopformula \stoptext gives the result in the attachment (I know I can typeset it by a combination of \circle and \int or something similar, my point is just to show the problem with \oint). Thanks for help, Best regards, Tomas ______________________________________________________________

Hi all,

I need to typeset some equations and I found out that these commands are undefined or don't work correctly (ver: 2009.04.17 19:32 MKIV):

iint, iiint, etc. oint, oiint, etc.

I don't know why iint and iint are failing. oiint is not defined in mkii, so there is no definition in mkiv. oint is working here.

Change the following in math-vfu

What is the prefered way of typesetting those symbols? (e.g. mathop{int !!! int} or something like that?)

It is more complicated, since you need to adjust for limits. These are defined in math-ini.mkiv, but for some reason the definitions are not kicking in.
