Accordingly A2 is called the Pauli algebra. The basis matrices are. σ0 = I = (1 0 0 1) σ1 = (0 1 1 0) σ2 = (0 − i i 0) σ3 = (1 0 0 − 1)
Involutory Transformations in the Projective Group and in its …
There exists a linear transformation f which sends e 1 to e 2, and sends e 2 to e 1, and which is the identity on all other basis vectors. It can be checked that f(f(x)) = x for all x in V. That is, f is an involution of V. For a specific basis, any linear operator can be represented by a matrix T. Meer weergeven In mathematics, an involution, involutory function, or self-inverse function is a function f that is its own inverse, f(f(x)) = x for all x in the domain of f. Equivalently, applying f … Meer weergeven Any involution is a bijection. The identity map is a trivial example of an involution. Examples of nontrivial involutions include negation ($${\displaystyle x\mapsto -x}$$), reciprocation ($${\displaystyle x\mapsto 1/x}$$), … Meer weergeven • Automorphism • Idempotence • ROT13 Meer weergeven • Ell, Todd A.; Sangwine, Stephen J.
