Gerschgorin and His Circles 1st ed. 2004, Corr. One of the most pleasing features of the book is what Varga calls the first recurring theme: every eigenvalue inclusion theorem has a corresponding nonsingularity theorem.

This book is a?ectionately dedicated to my mentors, Olga Taussky-Todd and John Todd. There are two main recurring themes which the reader will see in this book. The ?rst recurring theme is that a nonsingularity theorem for a mat- ces gives rise to an equivalent eigenvalue inclusion set in the complex plane for matrices, and conversely. Though common knowledge today, this was not widely recognized until many years after Ger? sgorin s paper appeared. That these two items, nonsingularity theorems and eigenvalue inclusion sets, go hand-in-hand, will be often seen in this book.

Whichever continuity is used in a proof of the Gerschgorin disk theorem, it should .

Whichever continuity is used in a proof of the Gerschgorin disk theorem, it should be justified that the sum of algebraic multiplicities of eigenvalues remains unchanged on each connected region Application. The Gershgorin circle theorem is useful in solving matrix equations of the form Ax b for x where b is a vector and A is a matrix with a large condition number. Varga, Richard S.

This book studies the original results, and their extensions, of the Russian mathematician, . Gerschgorin, who wrote a seminal paper, in 1931, on how to easily obtain estimates of all n eigenvalues (characteristic values) of any given n-by-n complex matrix. Since the publication of this paper, there hae been many newer results spawned by his paper, and this book will be the first which is devoted solely to this resulting area.
