38.1 Examples of Laurent series Example 38.1. Since ez = X ? n=0 zn n! = 1+z + z2 2 + z3 3! +··· for all z ? C, we have e1 z = X? n=0 1 n!zn = 1+ 1 z + 1 2z2 + 1 3!z3 +··· for all z withz| > 0. We shall see later that Laurent series expansions are unique, and so this must be the Laurent series representation for e1 z. In particular, we know that if C is a simple closed contour... 6 Laurent series and singularities 66 7 Cauchy’s Residue Theorem 75 8 Solutions to Part 1 99 9 Solutions to Part 2 103 10 Solutions to Part 3 111 11 Solutions to Part 4 120 12 Solutions to Part 5 127 13 Solutions to Part 6 130 14 Solutions to Part 7 135 c University of Manchester 2018 1.

Solution. Begin by converting this integral into a contour integral over Begin by converting this integral into a contour integral over C, which is a circle of radius 1 and center 0, oriented positively.... MATH 106 HOMEWORK 6 SOLUTIONS 1. (i) Give the Laurent expansion (in powers of z), representing the function f(z) = 1 z2 ?4z in certain domains, and specify these domains.

2.1 Example Determine the Laurent series for f(z) = 1 (z +5) (2) that are valid in the regions (i) fz : jzj< 5g, and (ii) fz : jzj> 5g. Solution The region (i) is an open disk inside a circle of radius 5, centred on z = 0, and the region (ii) is an open annulus outside a circle of radius 5, centred on z = 0. To make the series expansion easier to calculate we can manipulate our f(z) into a... Section 5.1 Cauchy’s Residue Theorem 101 Solutions to Exercises 5.1 1. Write f(z)= 1+z z = 1 z +1. f has one simpe pole at z0 = 0. The Laurent series expansion of f(z)atz0 = 0 is already given.

Both solutions contain a nonzero multiple of Y0(x), so both diverge as x > 0+, and this con?rms that the radius of convergence for both series is exactly 1. Alternative — Change of Variable.
