Pauli matrices. Wolfgang Pauli (1900–1958), c. 1924. Pauli received the Nobel Prize in physics in 1945, nominated by Albert Einstein, for the Pauli exclusion principle. In mathematical physics and mathematics, the Pauli matrices are a set of three 2 × 2 complex matrices which are Hermitian, involutory and unitary.

Then, using the theorem above, the corresponding elementary matrix must be a copy of the identity matrix 𝐼 , except that the entry in the third row and first column must be equal to − 2. The correct elementary matrix is therefore 𝐸 ( − 2) = 1 0 0 0 1 0 − 2 0 1 . .

Given a matrix \(A\), we can “find the transpose of \(A\),” which is another matrix. In this section we learn about a new operation called the trace. It is a different type of operation than the transpose. Given a matrix \(A\), we can “find the trace of \(A\),” which is not a matrix but rather a number.
