CHARACTERIZATION OF THE SEQUENTIAL PRODUCT ON
... As this is valid for all ρ we conclude that if AB = BA then (A ◦ B)◦C = A ◦ (B ◦ C). In fact, we shall only require a special case of this relation, together with the observation that A2 = A ◦ A. We thus state: Condition 3. (Weak associativity) A sequential product ◦ needs to satisfy the relation: A ...

... 1. Find all right inverses to the 1 × 2 matrix (row) A = (1, 1). Conclude from here that the row A is not left invertible. Solution: All right inverses of the matrix are (x, 1 − x)T , x ∈ R (taking all possible values of x we get all possible right inverses). The matrix is right invertible. If it is ...

... |Y ||X| , which is where the notation comes from.) This notation is sometimes helpful when talking about the cardinality of infinite sets. For instance, ℵ0 is the cardinal used to denote countable sets (like N, Z, or Q). The cardinal 2ℵ0 is the cardinality of all maps from N to 2. If you think about ...
