The double-, triple-, and quadruple-integrals (\iiiint) are undefined in basic ConTeXt's math. I must say thank you very very much!
In fact I've been looking for \iint in ConTeXt in the last two days -_- so i'll try to use \int\!\!\!\int instead of looking for a ConTeXt implementation :)
I met another problem today. Since there are not as many arrows in ConTeXt as there in AMS-LaTeX,I don't konw how to type the formula in the attached picture which will be referred in my presentation next Monday.
Hello, Xiao.
I'm glad I could help: I'm learning these advanced requirements as I go along. My personal mathematics needs are much more modest.
I wouldn't give up on ConTeXt just yet. Try: \loadmapfile[original-ams-base] \starttext \showmathcharacters Note the \formula{\rightleftharpoons} and \formula{\upharpoonleft\!\downharpoonright}. \stoptext
Do you know how you would code that cycle in (AMS)LaTeX? Hi, I can code the cycle in ConTeXt,but it's too ugly and I will try to improve it. here is my code:
\starttext \placeformula \startformula \matrix{A+B&{\Delta G_1\atop\rightleftharpoons}&AB\cr \Delta G_3\!\!\upharpoonleft\!\downharpoonright&& \upharpoonleft\!\downharpoonright\!\!\Delta G_4\cr A'+B&{\rightleftharpoons\atop\Delta G_2}&A'B\cr} \stopformula \stoptext There is a similar example in "The TeXbook"(example 18.46). You can try the follow code: $$\def\normalbaselines{\baselineskip20pt \lineskip3pt \lineskiplimit3pt } \def\mapright#1{\smash{ \mathop{\longrightarrow}\limits^{#1}}} \def\mapdown#1{\Big\downarrow \rlap{$\vcenter{\hbox{$\scriptstyle#1$}}$}} \matrix{&&&&&&0\cr &&&&&&\mapdown{}\cr 0&\mapright{}&{\cal O}_C&\mapright\iota& \cal E&\mapright\rho&\cal L&\mapright{}&0\cr &&\Big\Vert&&\mapdown\phi&&\mapdown\psi\cr 0&\mapright{}&{\cal O}_C&\mapright{}& \pi_*{\cal O}_D&\mapright\delta& R^1f_*{\cal O}_V(-D)&\mapright{}&0\cr &&&&&&\mapdown{\theta_i\otimes\gamma^{-1}}\cr &&&&&&\hidewidth R^1f_*\bigl({\cal O} _V(-iM)\bigr)\otimes\gamma^{-1}\hidewidth\cr &&&&&&\mapdown{}\cr &&&&&&0\cr}$$ Since i'm just a newbie of TeX, I don't really understand the first a few lines of the solution. I still need some learning and practice :)
