示例1: __init__
# 需要导入模块: from sage.all import ZZ [as 别名]
# 或者: from sage.all.ZZ import _generators_for_H [as 别名]
def __init__(self, p, congruence_type=1, sign=1, algorithm="custom", verbose=False, dump_dir=None):
"""
Create a Kamienny criterion object.
INPUT:
- `p` -- prime -- verify that there is no order p torsion
over a degree `d` field
- `sign` -- 1 (default),-1 or 0 -- the sign of the modular symbols space to use
- ``algorithm`` -- "default" or "custom" whether to use a custom (faster)
integral structure algorithm or to use the sage builtin algortihm
- ``verbose`` -- bool; whether to print extra stuff while
running.
EXAMPLES::
sage: from mdsage import *
sage: C = KamiennyCriterion(29, algorithm="custom", verbose=False); C
Kamienny's Criterion for p=29
sage: C.use_custom_algorithm
True
sage: C.p
29
sage: C.verbose
False
