Two-step Newton's method for deflation-one singular zeros of analytic systems
Kisun Lee, Nan Li, Lihong Zhi
We propose a two-step Newton's method for refining an approximation of a singular zero whose deflation process terminates after one step, also known as a deflation-one singularity.…

Isolating clusters of zeros of analytic systems using arbitrary-degree inflation
Michael Burr, Kisun Lee, Anton Leykin
Given a system of analytic functions and an approximation to a cluster of zeros, we wish to construct two regions containing the cluster and no other zeros of the system. The small…
