Introduction to Database Systems
... In order to understand the general procedure of matrix multiplication, we will introduce the concept of the product of a row matrix by a column matrix. A row matrix consists of a single row of numbers while a column matrix consists of a single column of numbers. If the number of columns of a row mat ...

THE K-THEORY OF FREE QUANTUM GROUPS 1. Introduction A
... In order to explain our notation let us briefly review some definitions. Given a matrix Q ∈ GLn (C), the full C ∗ -algebra of the free unitary quantum group FU (Q) is the universal C ∗ -algebra Cf∗ (FU (Q)) generated by the entries of an n × nmatrix u satisfying the relations that u and QuQ−1 are un ...
