Introduction into Noncommutative Algebra, Volume 1

I dedicated the volume $1$ of monograph ‘Introduction into Noncommutative Algebra’ to studying of algebra over commutative ring. The main topics that I covered in this volume: definition of module and algebra over commutative ring; linear map of algebra over commutative ring; vector space over associative division algebra; system of linear equations over associative division algebra; homomorphism of vector space over associative division algebra and covariance theory; eigenvalue and eigenvector over associative division algebra.
