[sage-support] Checking for convexity of Lattice Polytopes

2011-02-21 Thread Dmitri
ing I'm up against one of these scenarios: 1. I haven't searched thoroughly. 2. It's trivial to check for convexity. 3. It's a very hard problem. Does anyone have any suggestions or hints? Thanks! Dmitri -- To post to this group, send email to sage-support@googlegroups.com

think of a specific scenario: I'm working with tops of reflexive polytopes. One question that I'm interested is what results when we take the union of two tops. One obvious question to ask is whether it's convex or not. Thanks, Dmitri On Feb 21, 4:48 pm, Volker Braun wrote: &
