On Powers of Some Power Series
Powers Power Series
2010/11/9
We show that the compositions of positive integers may be interpreted in terms of powers of some power series, over arbitrary commutative ring. As consequences, several closed formulas for the composi...
On power series analytic in the open unit disk with finite doble-logarithmic order
Analytic in a disk maximum term central index jump points
2010/9/13
By introducing the concept of double-logarithmic order, we deal with intrinsic properties between maximum term and central index for a class of analytic functions with slow growth in the open unit dis...
