Words and symbols in linear algebra
1, the eigenvalue is a word. There is no special word eigen in mathematics. Eigenwerk does come from German vocabulary, and German is Eigenwerk.

Eigen stands for feature and Werk stands for value.

2. Stochastic processes can actually be used. However, the word "history" is more professional and a special word. Random has a wide meaning and is a general word.

Random is an English word, which comes from the Greek stochastikos.

I looked up Webster's Dictionary and found it.

In, random means involving random variables.

So here, randomness is more accurate than randomness.

3, r is the upper triangular matrix, also called the right triangular matrix.

4, p is the only invertible matrix.

I stands for identity matrix. So I can't be used.

If there is any relationship between invertibility and allowable matrix, there is a theorem: "If P is an allowable matrix, then P is also an invertible matrix, and its inverse matrix is P T."
