复变函数在不同圆环域内洛朗展开的探究
Research on Laurent series of complex functions in different annulus
摘要
Abstract
For the Laurent series of analytic functions in different circular domains with the same center,the rela-tionship between the difference of the coefficients of these Laurent series and the poles of the function between the two circular domains is given.In particular,the Laurent expansion of a rational function in a certain circular do-main can be directly obtained from its Laurent series in any circular domain with the same center.关键词
