FormalGroupLaws :: FormalSeries ^ ZZ

FormalSeries ^ ZZ -- powers of formal series

Synopsis

Description

i1 : R=ZZ[x,y]

o1 = R

o1 : PolynomialRing
i2 : s = series(x^2+x+y,2)

                   2
o2 = FormalSeries{x  + x + y, 2}

o2 : FormalSeries
i3 : s^4

o3 = FormalSeries{0, 2}

o3 : FormalSeries

Caveat

If n is 0, the formal series returned is 1 with the same precision as s. If n is negative, then s needs to have its constant part equal to either +1 or -1, otherwise an error occurs.
