Problems in Linear Algebra – Proskuryakov

In this post we will see Problems in Linear Algebra by I. V. Proskuryakov.

From the Preface:

In preparing this book of problems the author attempted firstly, to give a sufficient number of exercises for developing skills in the solution of typical problems (for example, the computing of determinants with numerical elements, the solution of systems of linear equations with numerical coefficients, and the like), secondly, to provide problems that will help to clarify basic concepts and their interrelations (for example, the connection between the properties of matrices and those of quadratic forms, on the one hand and those of linear transformations, on the other), thirdly to provide for a set of problems that might supplement the course of lectures and help to expand the mathematical horizon of the student (instances are the properties of the Pfaffian of the skew-symmetric determinant, the properties of associated matrices, and so on).

Compared with other problem book, this one has few new basic features. They include problems dealing with polynomial matrices (Sec. 13), linear transformations of affine and metric spaces (Secs. 18 and 19), and a supplement devoted to group rings, and fields. The problems of the supplement deal with the most elementary portions of the theory. Still and all, I think it can be used in pre-seminar discussions in the first and second years of study.

Starred numbers indicated problems that have been worked out or provided with hints. Solutions are given for a small number of problems.

The book was translated from the Russian by George Yankovsky and was first published by Mir Publishers in 1978.

Note: Though the file size is large (~ 2^ M) the scan quality is really poor and is barely readable at times. 2-in-1 page scan with lot of warping. We tried to rectify this but were unable to do so. There is a weird colour hue (pink and blue) on many of the pages. If any one has access to a better copy please let us know.
