In a paper by Burke, Lewis and Overton, a first order expansion has been given for the minimum singular value of A−zI, z ∈ C, about a nonderogatory eigenvalue λ of A ∈ Cn×n. This note investigates the relationship of the expansion with the Jordan canonical form of A. Furthermore, formulas for the condition number of eigenvalues are derived from the expansion.

Computational biology is an international collaboration. Open scholarly exchange nurtures the development of our field. And scientists are not the only beneficiaries; international cooperation is a crucial part of any country’s diplomatic relations. Our community, by actively engaging governments, needs to promote scientific exchange. In response to reports of visa difficulties, the Internation...
