WebIn the last lecture we saw that for 2nd order linear differential equations knowledge of one solution of the homogeneous equation suffices to provide the general solution to the inhomogeneous equation. In this lecture we study how to obtain systematically a solution of the homogeneous equation. 8. 1. Classification of Singularities 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.

WebSingular points are further classified as regular or irregular (or essential singularities): A singular pointx0 is regular if either p x or qx diverges there, but x xpx0 and 2 x xqx0 remain finite. A singular pointx0 is irregular if p x diverges faster than 0 1 x x so that In complex analysis, an essential singularity of a function is a "severe" singularity near which the function exhibits odd behavior. The category essential singularity is a "left-over" or default group of isolated singularities that are especially unmanageable: by definition they fit into neither of the other two categories of singularity that may be dealt with in some mann…
