**Isolated Singularities and Series Expansions**

7/07/2013 · I'm working on a few questions for an assignment but am unsure whether my approach to this type of question is sufficient or valid. I will show my solutions to two problems that are not part of the assignment just to ensure my method is correct. "...locate each of the isolated singularities......

**Isolated Singularities and Laurent Series**

In complex analysis, a branch of mathematics, an isolated singularity is one that has no other singularities close to it. In other words, a complex number z 0 is an isolated singularity of a function f if there exists an open disk D centered at z 0 such that f is holomorphic on D \ {z 0 }, that is, on the set obtained from D by taking z 0 out.... analyze isolated singularities, we shall need the following result. Theorem 1.3. Suppose f is continuous in a open set D and analytic in a deleted neighbourhood N of z0 ? D with N ? D. Then f is analytic at z0. The following result is immediate. Corollary 1.4. If f has an isolated singularity at z0, then it must be discontinuous at z0. Our ?rst task will be to describe all the di?erent

**On The Topology Of Isolated Singularities In Analytic**

isolated singularities is a topological invariant of a space; in particular, our results apply to all triangulations of spaces having this property. Highly connected (in the topological sense) spaces are the subject of Section 5.... Isolated Singularity. An isolated singularity is a singularity for which there exists a (small) real number such that there are no other singularities within a neighborhood of radius centered about the singularity.

**Isolated Singularities and Residues YouTube**

Isolated singularities. The function has an isolated singularity at if it is analytic on a deleted open neighborhood of , but is not analytic at . Example 8. 3. 1 has an isolated singularity at 0. has an isolated singularity at 2. Definition 8. 3. 2 Suppose that has an isolated singularity at . If... The Residue Theorem. Let C be a simple closed path.Suppose that f(z) is analytic on and inside C, except for a finite number of isolated singularities, z 1, z 2, …,z K inside C.

### Classi?cation of Singularities De?nition The Singularity at z0 of a function f(z) is said to be isolated if 9at least one neighborhood of z0 in which f(z) has no singularity other

- Under the condition of having strongly isolated singularities at infinity at a regular value c we give a sufficient condition expressed in terms of the total absolute curvature function to ensure the local triviality of the function f over a neighbourhood of c and doing so providing the tame version of Parusinski's Theorem on complex polynomials with isolated singularities at infinity.
