This is the command nef.x that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
nef.x, nef-<num>d.x - compute Hodge numbers of nef-partitions
SYNOPSIS
nef.x <Options>
DESCRIPTION
The nef-<num>d.x variant programs, where <num> is one of 4, 5, 6 and 11 work in different
dimensions ; nef.x defaults to dimension 6.
Options
-h prints this information
-f or -
use as filter; otherwise parameters denote I/O files
-N input is in N-lattice (default is M)
-H gives full list of Hodge numbers
-Lv prints L vector of Vertices (in N-lattice)
-Lp prints L vector of Points (in N-lattice)
-p prints only partitions, no Hodge numbers
-D calculates also direct products
-P calculates also projections
-t full time info
-cCODIM
codimension (default = 2)
-Fcodim
fibrations up to codim (default = 2)
-y prints poly/CWS in M lattice if it has nef-partitions
-S information about #points calculated in S-Poly
-T checks Serre-duality
-s don't remove symmetric nef-partitions
-n prints polytope only if it has nef-partitions
-v prints vertices and #points of input polytope in one line; with -u, -l the output
is limited by #points:
-uPOINTS
... upper limit of #points (default = POINT_Nmax)
-lPOINTS
... lower limit of #points (default = 0)
-m starts with [d w1 w2 ... wk d=d_1 d_2 (Minkowski sum)
-R prints vertices of input if not reflexive
-V prints vertices of N-lattice polytope
-Q only direct products (up to lattice Quotient)
-gNUMBER
prints points of Gorenstein polytope in N-lattice
-dNUMBER
prints points of Gorenstein polytope in M-lattice
if NUMBER = 0 ... no
0/1 info
if NUMBER = 1 ... no redundant
0/1 info (=default)
if NUMBER = 2 ... full
0/1 info
-G Gorenstein cone: input <-> support polytope
