Reviews

“This book presents some recent theoretical and computational results on Linear Algebra and Applications. The investigations developed in each one of its ten chapters have been written by one or more experts. They analyze subjects as quadratic forms, homogeneous matrix polynomials, linear control systems, Hermitian matrix-valued functions, triangular matrices, linear matrix equations, simultaneous triangularization over principal ideal domains and matrix differential equations, among others. Matrix Analysis Theory and Generalized Inverses are two extreme usefulness tools used to solve several of the proposed problems. In addition, settings such as the complex field or an arbitrary field, a ring or a quaternion algebra are the structures to work with. This interesting book is written in a very readable style and it is a very good contribution to the Linear Algebra Community and other interested readers.” -Nestor Thome, Professor, Department of Applied Mathematics of Polytechnical University of Valencia, Spain

“This is a worth-reading book about the recent developments in Linear Algebra and it includes contributions of fourteen authors from all over the world. The themes analyzed by the researchers in the ten chapters include quadratic optimization, matrix pencils, generalized inverses, matrix equations, maximal and minimal ranks and inertias, triangular matrices (tables) and their parafunctions, iterative methods, eigenvalues and eigenvectors, quasideterminants, regular rings and quaternions, among others. These developments have strong connections with other branches of mathematics like statistics, optimization, discrete mathematics and differential equations and they are related to important topics like fractals, graphs, power series, Markovian transitions and ODEs stability. Outside mathematics, potential applications to financial problems, electrical networks, filter design, chemical kinetics mechanisms and control theory, remark the importance of the topics considered. Finally, the inclusion of several open problems, numerical examples that clarify the theory and even a touch of humor in one of the footnotes, complete this interesting, enjoyable and easy readable book.”- Victor Martinez-Luaces, Profesor, Universidad de la RepÃºblica, Uruguay

“This book is a very interesting overview of recent topics of Linear Algebra and matrix Analysis. It includes topics such as Quadratic optimization, generalized inverses, Matrix Polynomials, Matrix functions, Iterative methods for solving matrix equations, simultaneous triangularization over a principal ideal domain, matrix differential equations and other very important topics. The book is quite easy to read and is written for postgraduate and/or PhD students, and researchers in the field of Linear Algebra. It includes theoretical investigations and many clarifying examples to support them, as well as numerical experiments presented. It can be used as a strong reference for scientific publications. Open problems on these topics are also presented and discussed.” -Dimitrios Pappas, Athens University of Economics and Business, Greece

“The book is devoted to advanced topics in Linear Algebra and its Application. It covers a broad range of topics. Some of them, for instance, paradeterminants and parapermanents, are not covered in the standard English books on the subject. Among the nice features of the book is the use of various tools of general algebra: fields, rings, quaternions, … The book is interesting and should be useful for experts and Ph.D. students in such areas of mathematics as PDE, control systems, graph theory, combinatorics, as well as in theoretical physics. It can also be of interest to engineers and researches working on the border between mathematics and chemistry, biology, or medicine.” – Professor Rostislav Grigorchuk, Mathematics Department of Texas A&M University

This book is written for a wide range of mathematicians, scientists dealing with linear algebra and its applications, and students which study linear algebra. It will be useful to all institutions where linear algebra and its applications are studied.
