2-codimensional tropical hypersurfaces

Postby ren » 25 Jul 2018, 22:13

I came across a tropical hypersurface which polymake claims to be two-codimensional (and not one-codimensional). Is this a bug or did I make some mistake in the input?

Code: Select all

tropical > $px = toTropicalPolynomial("min(13,x-y+5,-x+y+5,x-z+5,-x+z+5,x+5,-x+5)"); tropical > $Vx = new Hypersurface<Min>(POLYNOMIAL=>$px); tropical > print $Vx->DIM; polymake: used package ppl The Parma Polyhedra Library (PPL): A C++ library for convex polyhedra and other numerical abstractions. http://www.cs.unipr.it/ppl/ 1 tropical > print $Vx->AMBIENT_DIM; 3

Your input needs to be homogenized.
