I have a minimal working environment below.

It fails to be compiled.

Is the minipage compatible with xy matrix? What may be an alternative fix?

Thanks for the help!

documentclass[14pt]{article} 



usepackage[all, knot]{xy}

def Z{mathbb{Z}}







begin{document}





xymatrix{

&omega\

begin{minipage}[c]{5in}

1

end{minipage}ar[ru]&\

}





xymatrix{

&omega\

begin{minipage}[c]{5in}

$Delta=Z$:\

$boxed{delta}$

end{minipage}ar[ru]ar[rd]&\

&begin{minipage}[c]{5in}

$b=Z $:\

$boxed{delta(g,h)}$

end{minipage}\

}







end{document}

p.s. I may really need the 5 inch comment, since there is a long line of equation needs to be inserted there, like:

begin{minipage}[c]{5in}

abcdefghijklmnopqrstuvwxyzend{minipage}

There are two issues: one is that Xy-pic is not able to cope with cells so big as five inches.

However, I don't think you need a wide minipage, but rather an array; remember to brace it so as not to confuse Xy-pic.

documentclass{article}

usepackage{amsmath,amssymb,array}

usepackage[all,cmtip]{xy}



newcommand{Z}{mathbb{Z}}



begin{document}



xymatrix{

 & omega\

{begin{array}{@{}l@{}}

Delta=Z{:}\

boxed{delta}

end{array}}ar[ru]ar[rd]&\

&{begin{array}{@{}l@{}}

b=Z{:}\

boxed{delta(g,h)}

end{array}}

}
