Jp. Dedieu, CONDITION OPERATORS, CONDITION NUMBERS, AND CONDITION NUMBER THEOREM FOR THE GENERALIZED EIGENVALUE PROBLEM, Linear algebra and its applications, 263, 1997, pp. 1-24
We define the condition operators and the condition numbers associated
with a well-posed generalized eigenvalue problem, and we study the re
lationship between the condition numbers and the distance to the ill-p
osed problems. (C) 1997 Elsevier Science Inc.
