Modern Aspects of Linear Algebra
S. K. Godunov: Russian Academy of Sciences, Novosibirsk, Russia
This book discusses fundamental ideas of linear algebra. The author presents the spectral theory of nonselfadjoint matrix operators and matrix pencils in a finite dimensional Euclidean space. Statements of computational problems and brief descriptions of numerical algorithms, some of them nontraditional, are given.
Proved in detail are classical problems that are not usually found in standard university courses. In particular, the material shows the role of delicate estimates for the resolvent of an operator and underscores the need for the study and use of such estimates in numerical analysis.
Readership
Graduate students and research mathematicians working in linear algebra, differential equations, applied mathematics, and computational physics.
