7
9 sympow [options]
10
12 Mathematical package to compute special values of SYMmetric POWer el‐
13 liptic curve L-functions (up to about 64 digits of precision).
14
16 -bound #
17 an upper BOUND for how many ap to compute
18
19 -info [] []
20 only report local information for primes/sympows 1st argument is
21 prime range, 2nd is sympow range
22
23 -local only report local information (bad primes)
24
25 -curve []
26 input a curve in [a1,a2,a3,a4,a6] form
27
28 -label []
29 get a label to the given curve
30
31 -quiet turn off some messages
32
33 -terse turn on some messages: default
34
35 -verbose
36 turn on extra messages
37
38 -rootno #
39 compute the root number of the #th symmetric power
40
41 -moddeg
42 compute the modular degree
43
44 -analrank
45 compute the analytic rank
46
47 -sloppy []
48 for use with -analrank; have X sloppy digits
49
50 -nocm abort if curve has complex multiplication
51
52 -noqt ignore even powers of non-minimal quad twists
53
54 -noqdcheck
55 don't check if quad-double stuff works
56
57 -mdspeed []
58 speed for moddeg; 2.0 is default, 0.0 is proof
59
60 -hecke compute Hecke symmetric powers for a CM curve
61
62 -maxtable
63 set the max size of factor tables: 2^27 default
64
65 -sp [] argument to specify which powers this is a comma separated list
66 in each entry, the 1st datum is the sympow then could come b
67 which turns Bloch-Kato on then could come w# which specifies how
68 many tests then could come s# which says # sloppy digits then
69 must come p# which specifices the precision or P# which says ig‐
70 nore BOUND for this power then must come d# which says the de‐
71 rivative bound or D# which says do only this derivative (neither
72 need be indicated for even powers) default is
73 2w3s1p32,3bp16d1,4p8
74
75 -new_data []
76 will compute inverse Mellin transform mesh for the given data:
77 the format is [sp]d[dv]{h,c} sp is the symmetric power, dv is
78 the derivative, h indicates Hecke powers, and c indicates CM
79 case d[dv] is given only for odd or Hecke powers Examples: 1d3 2
80 2d1h 3d2 4 4c 5d0 6 7d0h 11d1 12c NOTE: new_data runs a shell
81 script that uses GP
82
83 -dump-endiantuple
84 display the endian-tuple, used as a component in the binary data
85 paths, and exit
86
87 -dump-versiontuple display the version-tuple (Major.minor.micro) and
88 exit
89
90 -version
91 print program version and exit
92
93 -help display this help and exit
94
95 Other options are used internally/recursively by -new_data
