Notes on typography:

Square brackets [ ] around matrices,
including column vectors, are generally omitted here.

The notation "V_k" is used to indicate "V" with subscript "k".
For example, if there are three variables in a linear equations
problem they will often be denoted x_1, x_2, x_3.
The notation "a^3" is used to indicate "a" with the superscript 3.
E.g., R^2 indicates the vector space of 2 by 1 real column vectors.
We use "u.v" to indicate the dot product of the vectors u and v.
In characteristic polynomial problems we use x instead of lambda.
