> How can I increase the thickness of arrows?
The answer is kinda clunky, but the following works well enough for me:
1. Put the following definition in your preamble:
2. Use \myar instead of \ar in all your xymatrix diagrams.
You'll need to use dvips output, as this command uses a postscript command
to enlarge the arrows, but it seems to work well enough.
Your question about making the xymatrix fill the page width is odd: an
xymatrix diagram has an intrinsic size, so there is no option to stretch
the diagram. Your best bet is to play with line and column spacing.
