nef.x, nef-<num>d.x - compute Hodge numbers of
nef-partitions
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.
- -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
