WebAn ODE (1) has singularities for finite under the following conditions: (a) If either or diverges as , but and remain finite as , then is called a regular or nonessential singular point. (b) If diverges faster than so that as , or diverges faster than so that as , then is called an irregular or essential singularity. WebThe term e1=z has an essential singularty at z= 0. Since the other two terms are analytic at z= 1, fhas an essential singurity at z= 0. The singularities at 1 and 1 + ican be analyzed in the same manner. (b) Find a function fthat has a removable singularity at z= 0, a pole of order 6 at z= 1 and an essential singularity at z= i. WebSo removable singularities are precisely the polesof order 0. A holomorphic function blows up uniformly near its other poles. If an isolated singularity a{\displaystyle a}of f{\displaystyle f}is neither removable nor a pole, it is called an essential singularity. dictionary profligate
