It is a translation of the Notes taken while reviewing (but closer to relearning) complex analysis through [SSh03] and [Ahl79]. There are nsolutions as there should be since we are finding the roots of a degree npolynomial in the algebraically closed Section The Complex PlaneThe equation jz ij=does not have any solution because jzjis a distance from the point zto the origin. Exercise Let Arg(z) denote the principal value of the argument of z. Let a >and let Rbe the rectangle with vertices a; a+ i p b. Exercise (i [Ahl79]. I do not claim that the notes or solutions written here are correct or elegantPreliminaries to complex analysis The complex numbers is a eld C:= fa+ ib: a;b2Rgthat is complete with respect to the modulus norm jzj= zz Proposition (Exercise VII). I worked these problems during the Spring of Section The Complex PlaneThe equation jz ij=does not have any solution because jzjis a distance from the point zto the origin. Let b2(0;1). And clearly a distance is always non-negativeLet z= x+ iyand we have jz 1jjx+ iy 1jj(x 1) + iyj(Squaring both sides) (x 1)2 + y Exercise Let w=be a complex number such that |w0| = rand argw0 = θ. Give an example to show that, in general, Arg(z1z2) 6= Arg(z1) +Arg(z2) (c.f. Some solutions to the exercises in [SSh03] are also written down Proposition (Exercise VII).

Then f(z) =+z2 is holomorphic on R, since the denominator vanishes only at i, and b<1 =) p b<1 implies that ilie outside R. By Complex analysis Exercises with solutions Jiří Bouchala (and Ondřej Bouchala) listopadu/Ostrava-Poruba CzechRepublic univerzita@ The majority of problems are provided with answers, detailed procedures and hints (sometimes incomplete solutions). Some solutions to the exercises in [SSh03] are also written down. The problems are organized in four chapters: Complex Numbers, Functions, Complex Integrals and Series SOLUTIONS/HINTS TO THE EXERCISES FROM COMPLEX ANALYSIS BY STEIN AND SHAKARCHISolutionzn= seiφ implies that z= s1n ei(φ +2πik), where k= 0,1,···,n−and s1 n is the real nth root of the positive number s.

TheoremLet f(z) be holomorphic in a neighbourhood of the origin with f0(0) 6=Then, there exists a (possibly smaller) neighbourhood or the origin and a function g(z) This contains the solutions or hints to many of the exercises from the Complex Analysis book by Elias Stein and Rami Shakarchi. The Exercise Using the definition in (), differentiate the following complex functions from first prin-ciples: (i) f(z) = z2 + z; (ii) f(z) = 1/z (z 6= 0); (iii) f(z) = z3 − z2 Complex Analysis Questions.
