示例1: next_frame
# 需要导入模块: from frame import Frame [as 别名]
# 或者: from frame.Frame import seed [as 别名]
def next_frame(self,length=infinity):
"""
Produce the child Frame in the tree of OM representations with the
partitioning from self.
This method generates a new Frame with the ``self`` as previous and
seeds it with a new approximation with strictly greater valuation
than the current one.
INPUT:
- ``length`` -- Integer or infinity, default infinity; The length of
the segment generating this factor. This is used to reduce the
total number of quotient with remainder operations needed in the
resulting Frame.
EXAMPLES::
sage: from sage.rings.polynomial.padics.factor.frame import Frame
sage: Phi = ZpFM(2,20,'terse')['x'](x^32+16)
sage: f = Frame(Phi)
sage: f.seed(Phi.parent().gen());f
Frame with phi (1 + O(2^20))*x
sage: f = f.polygon[0].factors[0].next_frame();f
Frame with phi (1 + O(2^20))*x^8 + (1048574 + O(2^20))
sage: f = f.polygon[0].factors[0].next_frame();f
Frame with phi (1 + O(2^20))*x^8 + (1048574 + O(2^20))*x^2 + (1048574 + O(2^20))
sage: f = f.polygon[0].factors[0].next_frame();f
Frame with phi (1 + O(2^20))*x^16 + (1048572 + O(2^20))*x^10 + (1048572 + O(2^20))*x^8 + (1048572 + O(2^20))*x^5 + (4 + O(2^20))*x^4 + (8 + O(2^20))*x^2 + (4 + O(2^20))
