Formal Power Series - an overview ScienceDirect Topics
WebRepresents the composed formal power series of two functions. Explanation. No computation is performed. Terms are calculated using a term by term logic, instead of a point by point logic. There are two differences between a FormalPowerSeries object and a FormalPowerSeriesCompose object. The first argument contains the outer function and … In mathematics, a formal series is an infinite sum that is considered independently from any notion of convergence, and can be manipulated with the usual algebraic operations on series (addition, subtraction, multiplication, division, partial sums, etc.). A formal power series is a special kind of formal series, whose … See more A formal power series can be loosely thought of as an object that is like a polynomial, but with infinitely many terms. Alternatively, for those familiar with power series (or Taylor series), one may think of a formal power series … See more One can perform algebraic operations on power series to generate new power series. Besides the ring structure operations defined above, we have the following. See more In mathematical analysis, every convergent power series defines a function with values in the real or complex numbers. Formal power series over certain special rings can also be interpreted as functions, but one has to be careful with the domain and codomain. … See more • Bell series are used to study the properties of multiplicative arithmetic functions • Formal groups are used to define an abstract group … See more If one considers the set of all formal power series in X with coefficients in a commutative ring R, the elements of this set collectively constitute another ring which is written $${\displaystyle R[[X]],}$$ and called the ring of formal power series in the variable X … See more Algebraic properties of the formal power series ring $${\displaystyle R[[X]]}$$ is an associative algebra over $${\displaystyle R}$$ which contains the ring $${\displaystyle R[X]}$$ of polynomials over $${\displaystyle R}$$; the polynomials … See more Formal Laurent series The formal Laurent series over a ring $${\displaystyle R}$$ are defined in a similar way to a formal power series, except that we also allow finitely many terms of negative degree. That is, they are the series that can … See more hallmark publishing submissions 2022
