Looking through "Rational Polyhedral Fans" and "Toric Varieties" pages there is a lot of information that can be calculated about fans/toric varieties but I have not found code to calculate the secondary fan.
I am looking for a simple way to do this either given a Toric variety (or its fan), or from starting from the set of $\beta$'s, as described in Chapter 14 of "Toric Varieties" by Cox, Little, Schenck.
Does anyone know if Sage has anyway to do this?Thu, 01 Jun 2017 10:52:35 -0500http://ask.sagemath.org/question/37758/is-there-a-way-to-compute-the-secondary-gkz-fan-with-sage/
