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

prints this information
use as filter; otherwise parameters denote I/O files
input is in N-lattice (default is M)
gives full list of Hodge numbers
prints L vector of Vertices (in N-lattice)
prints L vector of Points (in N-lattice)
prints only partitions, no Hodge numbers
calculates also direct products
calculates also projections
full time info
codimension (default = 2)
fibrations up to codim (default = 2)
prints poly/CWS in M lattice if it has nef-partitions
information about #points calculated in S-Poly
checks Serre-duality
don't remove symmetric nef-partitions
prints polytope only if it has nef-partitions
prints vertices and #points of input polytope in one line; with -u, -l the output is limited by #points:
... upper limit of #points (default = POINT_Nmax)
... lower limit of #points (default = 0)
starts with [d w1 w2 ... wk d=d_1 d_2 (Minkowski sum)
prints vertices of input if not reflexive
prints vertices of N-lattice polytope
only direct products (up to lattice Quotient)
prints points of Gorenstein polytope in N-lattice
prints points of Gorenstein polytope in M-lattice
0/1 info
0/1 info (=default)
0/1 info
Gorenstein cone: input <-> support polytope
