NEF.X(1) User Commands NEF.X(1) 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 SEE ALSO A complete manual is available here : http://arxiv.org/abs/1205.4147 nef.x 2.1 May 2012 NEF.X(1)
